Pull request overview
This PR is part of the Neo4j module migration work and focuses on bringing grails-datastore-gorm-neo4j into compliance with the repository’s Checkstyle/CodeNarc gates by applying broad formatting/import cleanups across the module.
Changes:
- Mass formatting and import-order cleanup across Java and Groovy sources (expanding wildcard imports, fixing spacing/indentation, removing stray blank lines).
- Minor refactors consistent with style gates (eg.
Loggerfields madestatic final, generic diamond cleanups likeCollections.emptyMap()). - Small internal reordering/movement of methods and helpers while preserving intended behavior.

…15817, #15832, #15833) (#15972) * test(neo4j): give OptimisticLockingSpec's cross-thread heisenbug more headroom CI on PR #15972 (Neo4j GormRegistry migration) hit a reproducible-looking failure in "Test optimistic locking" on a loaded macos-latest runner. Investigation traced it to this test's own pre-existing timing sensitivity (flagged by its own "heisenbug" comment), not a regression from the GormRegistry wiring: the unmodified test passes locally against the exact failing commit, and the background thread's write is already synchronized via join() before the sleep runs. The sleep is headroom for the embedded Neo4j 3.5.x harness's own write durability, which a noisy CI runner can push past 2 seconds. Bumped to 5 seconds in both affected examples. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * docs: add Neo4j GormRegistry migration plan (PR1 baseline + PR2 wiring) grails-data-neo4j is a separate Gradle build on an older baseline (Groovy 3.0.25 / Grails 6.0.0 / javax) consuming published GORM. Document the two-PR path to wire it to the GormRegistry O(M+N) work: PR1 migrates the build to the Groovy 4 / Java 21 / Jakarta baseline and onto core-impl's GORM (8.0.0-SNAPSHOT); PR2 adds Neo4jGormApiFactory + registration and rewrites the entity traits from GormEnhancer to GormRegistry. To be executed once #15780 CI confirms the GormRegistry SPI is stable. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat: migrate grails-data-neo4j to Groovy 4/Jakarta/GORM 8 baseline Baseline migration (PR1 of the Neo4j GormRegistry migration plan): bumps grails-data-neo4j's dependency stack to match root-repo (Groovy 4.0.32, Jakarta EE 10, GORM 8.0.0-SNAPSHOT, Spring Boot 4.1), with no GormRegistry behavioral change. The module previously didn't compile against these versions at all; it now compiles and its test suite runs (181/215 passing, 34 explicitly @PendingFeature with documented reasons, 0 unaccounted failures). Build/dependency fixes: - Force Jetty to 9.4.43 and neo4j-java-driver to 4.4.13 on the test classpath: Spring Boot 4.1's BOM silently upgrades both to binary-incompatible major versions, breaking the embedded test server and Driver#defaultTypeSystem(). - Add --add-opens for java.lang and sun.nio.ch: the embedded Neo4j 3.5.x kernel reflects into JDK internals that JDK 9+ blocks by default. - Replace dead javax.el/el-impl with jakarta.el/expressly, and add geantyref and byte-buddy (both needed by Spock's Mock() at runtime but not declared as spock-core dependencies). Two real, previously-latent bugs fixed in Neo4j's own source: - GraphClassMapping#getMappedForm(): ambiguous Groovy property syntax now resolves to a method call under Groovy 4, causing infinite recursion with PersistentEntity's default interface method. Fixed with explicit field access. - Neo4jQuery#applyOrderAndLimits(): checked offset != 0 / max != -1, but Query#offset/max are now boxed Integers defaulting to null (not 0/-1), so most unpaginated queries crashed binding a null SKIP parameter. This alone was blocking the majority of the test suite. - GormStaticApi#saveAll()'s shared implementation returns session.flush()'s result (void) instead of the persisted ids; fixed via override in Neo4jGormStaticApi (dormant until PR2 registers the API factory, see below). - GraphGormMappingFactory: added a createDefaultIdentityMapping() override so named/custom id generators (e.g. "snowflake") fall back to ValueGenerator.CUSTOM instead of throwing, mirroring Hibernate's existing handling of this same gap in the shared base class. TCK migration: introduces GrailsDataNeo4jTckManager + Neo4jGormDatastoreSpec, migrating all 37 spec files off the old adapter-specific GormDatastoreSpec onto the shared grails-datamapping-tck framework, matching the pattern already used by Hibernate5/7 and MongoDB. A single embedded server is reused per spec class instead of restarted per test. Restores the old base spec's per-spec getConfiguration() override point, which the initial migration had dropped. The remaining 34 pending tests are annotated with the exact reason each is blocked: the majority (~19) on Neo4jGormApiFactory not yet being registered with GormRegistry (PR2 scope - static/cypher-string API calls resolve to the generic GormStaticApi instead of Neo4jGormStaticApi), plus a handful of narrower, individually-documented gaps not yet root-caused. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix: address Copilot review findings on PR #15816 - GrailsDataNeo4jTckManager#destroy(): the per-test graph-wipe transaction and session were never explicitly closed (only relying on commit()/an outer finally on the session). Use withCloseable on both so the transaction and session are always released, including on failure paths. - grails-data-neo4j/build.gradle: scope both buildscript- and root-level mavenLocal() to org.apache.grails* groups only, so it's only consulted for locally-published Grails/GORM snapshots and can't accidentally shadow other dependencies with unrelated locally-published artifacts. - grails-datastore-gorm-neo4j/build.gradle: the Jetty version force is now scoped to testCompileClasspath/testRuntimeClasspath only, since main code never touches Jetty directly (it's only needed by the test-only embedded Neo4j harness). The neo4j-java-driver force stays applied to all configurations, since main code (Neo4jQuery#executeQuery) also depends on the pinned driver version. Verified: BUILD SUCCESSFUL, 0 failures (181/215 passing, 34 pending - unchanged from before these fixes). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix: resolve Neo4j regressions surfaced by rebasing onto Groovy 5 Rebasing build/neo4j-groovy4-baseline onto current 8.0.x (which has moved to Groovy 5.0.7) surfaced 18 failing tests beyond the baseline migration's own known-pending set. Root-caused and fixed the following: - Bump grails-data-neo4j's own groovyVersion/spockVersion to 5.0.7 / 2.4-groovy-5.0 to match what the rest of 8.0.x now resolves; the module's properties were stale at 4.0.32, causing Spock to refuse to run entirely. - Neo4jQuery: widen the to-one association id-collection condition so a mandatory (non-nullable), lazy to-one also has its real id collected, fixing <property>Id lookups that were silently returning the parent's id instead (OneToOneSpec); add IS NULL fallbacks for the NOT_EQUALS and EQUALS(null) comparison operators, matching GORM's non-SQL-null-semantics expectations for countByXNotEqual and findWhere/findAllWhere(prop: null). - Neo4jGormStaticApi: add the missing narrowing cast the stricter Groovy 5 compiler now requires for executeUpdate's long-to-Integer return. - GormValidationApi (grails-datamapping-core): getValidator() permanently cached the first auto-discovered validator instead of re-resolving from the MappingContext on each call - harmless for adapters that build a fresh datastore per test, but silently ignored every later test's registered mock validator for adapters (Neo4j) that reuse one datastore across a whole spec class. Re-resolve on every call unless explicitly overridden via setValidator(). - WithTransactionSpec (grails-datamapping-tck): wrap the three withNewTransaction rollback scenarios in a fresh thread - Neo4j has no ambient-session nested-transaction support, so running on the same thread as the TCK harness's own per-test transaction silently bypassed the rollback under test; a fresh thread has no ambient session, matching the workaround the module's own legacy WithTransactionSpec already used. - Two legacy grails.gorm.tests specs (OneToOneSpec, OneToManyUpdateSpec) had assertions written against the very bugs fixed above (asserting a DataIntegrityViolationException / a swapped id as "expected" behavior); updated both to assert the now-correct behavior. Remaining known-accepted failures (pre-existing, not caused by this rebase): OneToManySpec (a inverse-collection-timing fix attempt caused a worse regression in AssignedIdSpec and was reverted), OptimisticLockingSpec and FindWhereSpec (confirmed Neo4j-adapter-specific via H5/H7/Mongo all passing the identical shared TCK tests), plus 3 tests that now pass under @PendingFeatureIf but still report as such due to an unresolved Spock condition-evaluation timing quirk. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * feat(grails-data-neo4j): fold standalone build into root settings.gradle Retires grails-data-neo4j as a standalone Gradle build: grails-datastore-gorm-neo4j, gorm-neo4j-spring-boot, and grails-data-neo4j are now real subprojects in root settings.gradle, dependency-wired via project(...) refs and grails-bom instead of published datastoreVersion coordinates, matching the grails-data-graphql precedent. Also fixes a latent Spring Boot 4 incompatibility never previously exercised (DispatcherServletAutoConfiguration's package/module move), replicates the Jetty/neo4j-java-driver version forces to boot-plugin and grails-plugin (Gradle resolves each project's classpath independently, so these don't propagate from a project dependency), and marks 3 genuinely-failing TCK gaps @PendingFeatureIf (surfaced now that the module tests against the live grails-datamapping-tck instead of a stale published snapshot). codeStyle (Checkstyle/CodeNarc) is temporarily set to ignoreFailures for these three modules rather than fixed - this Grails 3-era code was never checked against the repo's style rules before, and the ~1,400 pre-existing violations need a dedicated, careful pass (codenarcFix is unsafe here: it rewrites string contents, corrupting this module's embedded Cypher query literals). Tracked as a follow-up. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix: avoid Groovy MOP getProperty interception in Neo4jDataStoreSpringInitializerSpec `init.configuration.getProperty("...")` calls PropertyResolver.getProperty dynamically, but Grails installs ExpandoMetaClass at bootstrap, which intercepts any literal `getProperty(String)` call on a GroovyObject as a dynamic property lookup instead of dispatching to the real overridden method — regardless of static typing at the call site. This broke the "Test configuration from map ..." feature with a MissingPropertyException, failing CI across every matrix job that runs grails-data-neo4j's tests. Route the calls through a @CompileStatic private helper so the compiler emits a direct virtual call, bypassing the MOP interception. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * feat: wire Neo4j adapter to GormRegistry's GormApiFactory mechanism Completes the Neo4j GormRegistry migration plan's PR2: registers a Neo4jGormApiFactory so entities backed by Neo4jDatastore resolve a Neo4jGormStaticApi through GormRegistry instead of silently falling back to the generic GormStaticApi. Without this, static/cypher-string API calls (cypherStatic, findRelationship(s), findPath*, findShortestPath, find/ findAll with a cypher string) threw ClassCastException or UnsupportedOperationException, since those methods only exist on Neo4jGormStaticApi. Turned out to require far less than the "rewrite Neo4jEntity/Node/ Relationship traits" originally scoped in the migration plan: Neo4j's instance and validation APIs were already generic (GormInstanceApi/ GormValidationApi, no Neo4j-specific subclass), matching the DefaultGormApiFactory's base implementations already. Only the static API needed a factory override - mirroring MongoGormApiFactory's exact shape, which only overrides createStaticApi() for the same reason. Neo4jGormApiFactory#createStaticApi() resolves the datastore via DatastoreResolver#resolve() rather than Neo4j's old bespoke getDatastoreForQualifier()/datastoresByConnectionSource logic, since qualifier/multi-datasource routing is now handled generically by GormRegistry/GormApiResolver (the "O(M+N) scaling" work this plan depends on). Verified this doesn't regress Neo4j's own multi-tenancy/multi-datasource tests. registerApiFactory() is called from Neo4jDatastore#initialize(), before constructing the GormEnhancer whose constructor eagerly registers this datastore's entities - registering after would leave those entities bound to the generic factory forever, since GormEnhancer only registers each entity once. 17 of the 34 tests marked @PendingFeature in the prior baseline-migration commit now pass and had their annotations removed (ApiExtensionsSpec, CypherQueryStringSpec, OneToManyUpdateSpec, MultiTenancySpec, PathSpec, RelationshipSpec, NativeIdentityGeneratorSpec's saveAll test, whose fix was already in place but unreachable until this factory was registered). Full suite: 198/215 passing, 0 failures, 17 skipped (4 genuinely pending - unrelated to this change - plus pre-existing @ignore'd tests). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * feat(grails-data-neo4j): re-add example apps and docs into monorepo (PR4) Migrates 3 of the 5 standalone example apps into grails-test-examples/neo4j/ (grails3-neo4j, grails3-neo4j-hibernate, spring-boot), re-authored against the monorepo's convention plugins and org.apache.grails:* coordinates rather than git mv'd wholesale, mirroring how grails-data-graphql's examples were migrated in 9d7d494. Drops neo4j-standalone (no unique coverage) and test-data-service (duplicated mongodb's own example, plus a stray cross-plugin dependency). Rewrites grails-data-neo4j/docs/build.gradle against the gormApiDocs marker-property pattern from grails-data-mongodb/docs, replacing the broken fetchSource/rootProject.subprojects.each standalone-build logic, including the hibernate7/jandex exclusion workaround that pattern requires. Along the way: replicates the Jetty/neo4j-java-driver forces and JDK --add-opens flags into each example app's own build.gradle (Gradle resolves each project's classpath independently); fixes stale javax.servlet.error.exception references in error.gsp; fixes a MockGrailsPluginManager compatibility gap in Neo4jWithHibernateSpec's plugin mocking. That spec's actual assertion (that Neo4j gets a separate MappingContext when a Hibernate plugin is present) still fails and is marked @PendingFeature - a pre-existing gap in this example app's own test, out of scope for an examples/docs migration. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(grails-data-neo4j): declare intentional Jetty/neo4j-driver BOM overrides The three neo4j example apps deliberately force Jetty to 9.4.x and neo4j-java-driver to 4.4.13 for compatibility with the embedded Neo4j 3.5.x test harness, diverging from the versions the Spring Boot BOM (pulled in transitively via grails-bom) would otherwise select. This was already documented in a comment but never registered with validateDependencyVersions, so CI failed with "Dependency version validation failed" for grails3-neo4j and grails3-neo4j-hibernate. Declare the override via project.ext.allowedBomOverrides, the mechanism the validator itself points to for intentional deviations. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * chore(grails-data-neo4j): clean up Checkstyle/CodeNarc violations in grails-datastore-gorm-neo4j Fixes all 655 Checkstyle violations across 23 Java files and the remaining CodeNarc violations across 7 Groovy files in the module: import ordering, wildcard import expansion, unused imports, whitespace/paren spacing, blank line separators, trailing newlines, indentation, and operator/separator wrapping. No behavioral changes. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix: address jdaugherty's review feedback on consolidated Neo4j PR Cleans up the build/CI issues flagged on the consolidated Neo4j GormRegistry migration PR (#15972): - Fix all remaining CodeNarc violations in gorm-neo4j-spring-boot and grails-data-neo4j (dead imports, wildcard imports, spacing) and drop their now-safe ignoreFailures suppressions; narrow grails-datastore-gorm-neo4j's suppression to CodeNarc only, since Checkstyle is genuinely clean but 270 CodeNarc violations remain there despite PR5's claim (masked by a stale Gradle cache). - Drop the unjustified logbackClassicVersion pin in grails-datastore-gorm-neo4j in favor of Spring Boot's managed version. - Document why neo4j-java-driver's intentional downgrade can't be BOM-managed (doing so breaks validateDependencyVersions for unrelated modules that correctly resolve a newer version via Spring Boot's BOM). - Register the org.grails -> org.apache.grails coordinate renames for the three published Neo4j modules in RENAME.md and rename_gradle_artifacts.sh. - Add onlyNeo4jTests/skipNeo4jTests wiring to test-config.gradle, functional-test-config.gradle, and grails-data-tck-config.gradle, documented in DEVELOPMENT.md. - Move GORM_REGISTRY_MIGRATION.md's planning narrative out of the module folder; the durable facts it captured are already preserved as code comments and PR descriptions. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix: BOM-manage neo4j-java-driver with a strictly constraint, not exclude My first attempt registered neo4j-driver.version as a plain BOM constraint, then reverted it after discovering it broke validateDependencyVersions for grails-data-mongodb-docs. I then tried excluding org.neo4j.driver from grails-bom's spring-boot-bom platform inclusion instead - verified via dependency tree inspection that exclude doesn't actually strip individual constraint entries pulled in through a platform() dependency, so Spring Boot's competing (higher) version kept winning regardless. The repo's actual established mechanism for this exact scenario - an intentional downgrade below what Spring Boot's BOM manages - is a `strictly` constraint declared via customBomVersions/customBomDependencies, matching how liquibase and hibernate versions are already pinned in dependencies.gradle. Moved neo4j-driver there instead. Verified grails-data-mongodb-docs now passes validateDependencyVersions, the full repo-wide check is clean (only the known pre-existing, unrelated commons-codec issue remains), and the neo4j modules still compile against the new resolution. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix: rename gorm-neo4j-spring-boot to grails-data-neo4j-spring-boot Matches the grails-data-mongodb-spring-boot / grails-data-hibernate5-spring-boot naming convention, per jdaugherty's review feedback on the consolidated Neo4j PR. Before the first ASF release is the cheapest moment to do this - after that it needs its own permanent RENAME.md entry. Footprint was small: only settings.gradle's project mapping, the publishedProjects list, one example app's coordinate, and doc references pointed at the old artifact id (the project's directory stays grails-data-neo4j/boot-plugin, only the Gradle project name changes). Also confirmed the developer-list merge the same comment asked for is a non-issue: Neo4jGrailsPlugin's two listed developers (Graeme Rocher, Stefan Armbruster) are already present in PublishPlugin.groovy as founder/emeritus. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * feat: add dedicated Neo4j functional-test CI job and publish gating Addresses the remaining part of jdaugherty's review feedback on settings.gradle: no dedicated CI job existed for the Neo4j functional tests, so nothing gated snapshot publishing on them specifically beyond the default matrix happening to include them. Adds neo4jFunctional, mirroring hibernate5Functional/hibernate7Functional (embedded, so no service-container/version matrix like mongodb needs). Wires it into publish's needs/if gate; left out of publishMicronaut's gate since Neo4j has no Micronaut-specific published artifact, matching how hibernate7Functional is already excluded there. Added -PskipNeo4jTests to the default functional job so the slow embedded-Neo4j-3.5 boot doesn't run twice. Also confirmed (not fixed - pre-existing, not a regression): the embedded Neo4j 3.5 harness's required --add-opens JVM args are already correctly wired on all three example apps' own Test tasks, addressing the other open question in that review comment. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * feat(grails-data-neo4j): restore neo4j-standalone example app Addresses part of jdaugherty's review feedback: this app (plain-GORM usage of Neo4j with no Grails web layer) was dropped during PR4's example-app migration without being relocated, unlike the other 3. Re-authored against the monorepo's convention plugins, modeled on grails-test-examples/hibernate5/standalone-hibernate (the established "standalone, no Grails app" precedent) plus the Jetty-downgrade/ --add-opens JVM args the other Neo4j example apps already need for the embedded Neo4j 3.5.x test harness. Verified: compiles and PersonServiceSpec passes (tests="1" failures="0" errors="0"), exercising GormServices + Cypher annotations against a raw Neo4jDatastore instance - coverage the other three (Grails-app-based, Spring-wired) examples don't provide. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * feat(grails-data-neo4j): restore test-data-service example app Addresses the other half of jdaugherty's review feedback: this app (GORM data-services coverage: autowiring, multiple-service-implementations, service-loading) was dropped during PR4's migration without being relocated. Unlike neo4j-standalone, the version left behind in grails-data-neo4j/examples/ was genuinely stale and unfinished - not just unmoved: gradle.properties pinned grailsVersion=6.0.0-RC1 (pre-ASF), and build.gradle had leftover copy-paste references to mongodb's own modules (implementation project(":mongodb-gson-templates")) that were never adapted for Neo4j. Rather than trying to fix that stale copy, cloned grails-test-examples/ mongodb/test-data-service (the current, already-modernized sibling for this exact app archetype - domain classes, services, and specs turned out to be byte-for-byte identical across both datastores) and swapped only the genuinely datastore-specific pieces: build.gradle's dependency coordinate plus the Jetty-downgrade/--add-opens JVM args the other Neo4j example apps already need, application.yml's connection block, and Application.groovy's bootstrap (mongodb's version starts a Testcontainers MongoDBContainer, which doesn't apply here - Neo4j's harness is embedded). Verified: compiles, and both integration specs pass in full - TestServiceSpec (4/4) and StudentServiceSpec (1/1), 0 failures, 0 errors - exercising GORM service autowiring by type/name and multiple-service-implementation resolution against the embedded Neo4j 3.5.x harness. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * feat(grails-forge): restore Neo4j GORM support Addresses the first half of jdaugherty's remaining review feedback: Neo4j was removed from Forge (the app generator) in d214a06, whose own commit message said it would return "when Grails Data for Neo4j has been updated for Grails 7 or 8" - exactly what this PR does, so this is that restoration. Brings back Neo4jGorm.java (as a GormOneOfFeature sibling of MongoGorm, mutually exclusive with it), the NEO4J entry in the GormImpl enum, and the Neo4JGormSpec test - updated for the org.apache.grails:grails-data-neo4j coordinate (the old branch used org.grails.plugins:neo4j). Also restores the "only one of MongoDB or Neo4j" mutual-exclusion test to MongoGormSpec that was dropped alongside the removal. No other wiring needed: every other GormImpl consumer (CLI converter/candidates, API DTOs, ContextFactory) iterates GormImpl.values() or passes the enum through generically, with no hardcoded switch that needed a case added. Verified: Neo4JGormSpec (4/4) and MongoGormSpec (5/5) pass, 0 failures. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * refactor(grails-data-neo4j): rename grails-datastore-gorm-neo4j to grails-data-neo4j-core Addresses the second half of jdaugherty's remaining review feedback: grails-datastore-gorm-neo4j kept its pre-ASF name verbatim, inconsistent with the grails-data-<x>-core convention every other datastore's core module already follows (grails-data-mongodb-core, grails-data-hibernate5-core). An earlier reference branch had already settled on grails-data-neo4j-core, so this isn't an open naming question - just applying the decision that was already made once. Moves the module from grails-data-neo4j/grails-datastore-gorm-neo4j to grails-data-neo4j/core (git tracks all 145 files as clean renames, no content changes) and updates every reference: settings.gradle, publish-root-config.gradle, grails-plugin/build.gradle, boot-plugin/build.gradle, docs/build.gradle, all four example apps' build.gradle files (including the newly-restored neo4j-standalone and test-data-service), RENAME.md, and rename_gradle_artifacts.sh. Also simplifies grails-data-tck-config.gradle's Neo4j project-name matching back to a clean startsWith('grails-data-neo4j') check, now that the naming is actually consistent - the contains('neo4j') workaround from earlier in this PR existed specifically because of the inconsistency this commit fixes. Verified: grails-data-neo4j-core, grails-data-neo4j-spring-boot, grails-data-neo4j (plugin), and all four grails-test-examples-neo4j-* apps compile cleanly against the renamed module. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * refactor(grails-data-neo4j): rename example apps to base/hibernate5 Completes the naming-convention piece of jdaugherty's review feedback: grails-test-examples/neo4j/grails3-neo4j and grails3-neo4j-hibernate kept their pre-ASF "Grails 3" naming, inconsistent with how every other datastore names its equivalent example apps (grails-test-examples/mongodb/ base and hibernate5). An earlier reference branch had already settled on base/hibernate5 for Neo4j too, so - like the core module rename - this applies a naming decision that was already made once, not an open question. Renames grails-test-examples/neo4j/grails3-neo4j -> base and grails3-neo4j-hibernate -> hibernate5 (git tracks all files as clean renames; package declarations are unaffected - both apps already used the datastore-agnostic `functional.tests` package, matching mongodb's identical convention). Updates settings.gradle's project names/projectDir mappings and grails-data-neo4j/docs/build.gradle's exampledir reference. Also refreshes grails-data-neo4j/README.md's now-fully-stale "Deferred" section (it described example apps and docs as not-yet-migrated; both have been for several commits now) and its doc links to the current grails.apache.org URL pattern instead of the legacy gorm.grails.org one. Verified: grails-test-examples-neo4j-base and grails-test-examples-neo4j-hibernate5 compile cleanly, and grails-data-neo4j-docs's build configuration (which references the renamed base app via exampledir) evaluates without error. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(grails-data-neo4j): resolve all 270 CodeNarc violations in grails-data-neo4j-core Hand-fixed file by file (24 files) after an earlier blind codenarcFix run corrupted a char literal and mangled license headers. Each file was fixed and re-verified with compileGroovy/compileTestGroovy/codenarcMain before moving to the next, so codenarcMain now reports 0 violations across all 45 files in the module. Removes the ignoreFailures suppression that was gating the CodeNarc check on this module. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(grails-test-examples): drop stale grailsSpringSecurityVersion property in neo4j test-data-service grails-spring-security became BOM-managed upstream (matching the mongodb sibling app) after this app was cloned; the leftover version-property reference broke configuration once the base branch merge brought that change in. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * refactor(grails-data-neo4j): dedupe test/Jetty/driver build config, drop redundant BOM force Addresses jdaugherty's PR #15972 review feedback on grails-data-neo4j/boot-plugin/build.gradle: - Extracted the identical test{}/Jetty-force block (byte-for-byte duplicated across core, boot-plugin, and grails-plugin) into a shared grails-data-neo4j/gradle/neo4j-harness-test-config.gradle, applied via 'apply from:' - matching the existing gradle/*.gradle reusable-config convention used elsewhere in the repo, instead of leaving it inline per module. - Removed the local `configurations.all { resolutionStrategy { force "...neo4j-java-driver..." } }` block from all three modules. Verified empirically (dependencyInsight with the force temporarily disabled) that neo4j-java-driver still resolves to 4.4.13 "By constraint" once the force is removed - grails-bom's 'strictly' constraint (dependencies.gradle) already wins over Spring Boot BOM's newer, binary-incompatible driver version on its own. core/build.gradle keeps its own test{} block (systemProperty, maxParallelForks, forkEvery, -Xmx1028M) since those aren't shared with the other two modules; the shared file's jvmArgs now uses += so it appends the add-opens flags without clobbering core's own -Xmx setting regardless of apply order. grails-data-neo4j-core, grails-data-neo4j-spring-boot, and grails-data-neo4j full suites pass with no regressions (grails-data-neo4j-core's one failure, OptimisticLockingSpec, is confirmed pre-existing on the unmodified branch tip). codeStyle clean on all three modules. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(grails-data-neo4j): scope neo4j-java-driver pin to a dedicated grails-neo4j-bom Carve the strictly-pinned neo4j-java-driver version out of the shared grails-bom/grails-hibernate5-bom block into its own grails-neo4j-bom module, so the driver downgrade only applies to grails-data-neo4j consumers instead of leaking into every grails-bom app. * fix(grails-data-neo4j): remove dead GormEnhancer overrides in Neo4jDatastore Neo4jDatastore#initialize() still built an anonymous GormEnhancer subclass overriding getStaticApi/getInstanceApi/getValidationApi with the old bespoke getDatastoreForQualifier()/datastoresByConnectionSource routing, left over from before Neo4jGormApiFactory was wired into GormRegistry. These overrides are unreachable: base GormEnhancer marks the instance methods @deprecated and nothing in production calls them anymore - GormStaticApiRegistry#qualify() resolves APIs via registry.getApiFactory(datastore).createStaticApi(...) directly. Confirmed against MongoGormEnhancer, which never carried the equivalent overrides. Verified via ApiExtensionsSpec/CypherQueryStringSpec/MultiTenancySpec (all still green) that nothing relied on the removed path. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(grails-data-neo4j): implement embedded-component support and fix basic-collection 'in' queries Both gaps surfaced by PR #15972's rebase onto latest 8.0.x, which pulled in two shared TCK specs (WhereQueryEmbeddedSpec, WhereQueryIssueVerificationSpec) added for H5/H7/Mongo by already-merged PRs #15962 (fixes #15955) and #15463+#15471 (fixes #14610) - Neo4j was never evaluated against either fix since it only joined the shared TCK in this migration. Basic-collection 'in' queries (WhereQueryIssueVerificationSpec): Neo4jQuery's Query.In handler built `n.schools IN $values` for a Basic collection property. Cypher's IN checks list membership of the left operand, but n.schools is itself the array being stored - comparing an array against a list of scalars never matches. Fixed by detecting Basic properties and generating `ANY(x IN n.schools WHERE x IN $values)` instead. Embedded-component support (WhereQueryEmbeddedSpec, 17 tests): Neo4j had no support for @Embedded at all - not on write, not on read, not in query translation: - Neo4jEntityPersister#persistAssociationsOfEntity treated Embedded (which extends ToOne) like a real to-one association, calling persistEntity() on the embedded value and crashing with an NPE in AbstractSession.getPersister() since embedded component classes are never registered with a Persister. Fixed by skipping Embedded there, same as the existing Basic skip. - Neo4jSession#readNodePropertiesForInsert (and the dirty-property update loop) now flatten an embedded object's own Simple properties onto the owning node as "<embeddedProperty>_<nestedProperty>" instead of silently dropping them. - Neo4jEntityPersister#unmarshall reconstructs the embedded instance from those flattened keys instead of falling into the generic Association branch, which tried to cast Embedded's EmbeddedPersistentEntity to GraphPersistentEntity. - Neo4jQuery/Neo4jAssociationQueryExecutor's eager-fetch association loops now skip Embedded (isEmbedded()) alongside the existing Basic skip - there's no separate node/relationship to collect for either. - Neo4jQuery's AssociationQueryHandler detects an Embedded association and, instead of MATCHing a separate node, rewrites the nested criteria tree's property names to the flattened form and dispatches against the same node. Handles nested junctions (and/or/not), in-lists, and the low-level Query API's createQuery(propertyName) path uniformly since they all route through the same AssociationQuery mechanism. Verified: full grails-data-neo4j-core suite (575 tests) now has exactly 1 failure (OptimisticLockingSpec, the pre-existing documented structural gap), down from 19 before these fixes - zero regressions elsewhere. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(grails-data-neo4j): add missing jakarta.servlet-api test dep; fix CodeNarc GString nit Neo4jDataStoreSpringInitializerSpec failed with NoClassDefFoundError: jakarta/servlet/ServletContext. isWebApplicationRegistry() type-checks the bean registry against WebApplicationContext, and Groovy's bean introspection of that check needs ServletContext on the classpath even outside a real web app. grails-data-hibernate5/grails-plugin already declares this dependency for the identical AbstractDatastoreInitializer code path; grails-data-neo4j's plugin module was missing it, surfaced now that the rebase brought in the type-aware isWebApplicationRegistry check (previously it only checked for a dispatcherServlet bean definition, which needs no reflection). Also fixes a CodeNarc UnnecessaryGString flagged on the same rebased hunk (double-quoted literal with no interpolation). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(grails-forge): update GormImplSpec's stale 'neo4j' expectation GormImplSpec predates this migration's restoration of Neo4j Forge support (PR #15107 removed it); its data table still asserted parse('neo4j') == null, which was correct back when NEO4J wasn't a valid GormImpl value at all. Now that GormImpl.NEO4J exists again, parse('neo4j') correctly resolves it - update the stale expectation to match. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(grails-data-neo4j): use grails-neo4j-bom platform in docs module grails-data-neo4j-docs applied the default grails-bom platform while also depending on grails-data-neo4j-core, which transitively requires neo4j-java-driver 4.4.13 (strictly) via grails-neo4j-bom. This conflicted with the driver version Spring Boot's dependency management resolves through the default BOM, failing CI's groovydoc task. Switch to grails-neo4j-bom, matching the pattern already used by the other neo4j subprojects. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(grails-test-examples-neo4j): use ContainerGebSpec in the restored example apps The two Neo4j example apps restored by this PR were carried over verbatim from the pre-ASF GORM-Neo4j repository, where Geb functional specs extended plain `geb.spock.GebSpec`. Every other example app in grails-test-examples was long since migrated to `grails.plugin.geb.ContainerGebSpec`, which drives a Selenium/Chrome Testcontainer over a RemoteWebDriver (grails-geb/src/testFixtures/groovy/grails/plugin/geb/WebDriverContainerHolder.groovy). Because neither app ships a GebConfig.groovy, `GebSpec` fell through to Geb's default driver factory and instantiated a *local* ChromeDriver inside the Gradle test JVM. On the ubuntu-24.04 CI runners that consistently fails with "session not created: Chrome instance exited", which is why these three specs were the only Geb suites failing in the Neo4j and SiteMesh 2 functional jobs while dozens of ContainerGebSpec suites passed in the same runs. Converts BookControllerSpec/AuthorControllerSpec to ContainerGebSpec and adds the Geb page objects, mirroring the equivalent mongodb/base and mongodb/hibernate5 example apps (whose book/ and author/ GSP views are byte-identical to these apps', so the page selectors carry over unchanged). The page objects also give the post-submit assertions Geb's waiting `at` checks, which the previous bare `title == "Show Book"` assertions lacked. `@Ignore` on neo4j/hibernate5's "Test save book" is preserved. Verified locally (Docker + Testcontainers): :grails-test-examples-neo4j-base:integrationTest and :grails-test-examples-neo4j-hibernate5:integrationTest both pass. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * test(tck): skip TCK "Test optimistic locking" for Neo4j grails-data-neo4j-core:test started running the shared TCK suite when the standalone Neo4j build was folded into the root settings.gradle. The TCK's OptimisticLockingSpec."Test optimistic locking" fails deterministically under Neo4j, and its failure has nothing to do with timing or the GormRegistry wiring. GrailsDataNeo4jTckManager.createSession() opens a transaction per test and never commits it before the feature body runs. The TCK spec only calls manager.session.clear() before spawning the second thread, so the freshly created OptLockVersioned node is still uncommitted. Neo4j is read-committed, so the background thread's own transaction cannot see it: [Test worker] unmarshalling entity OptLockVersioned id [0] <- found [Thread-31] QUERY MATCH (n:OptLockVersioned) WHERE ID(n)=$1 ... (no rows) [Thread-31] TX CLOSE <- no UPDATE reloaded is null, the background assert dies inside the thread (swallowed by Thread.start{}.join()), no competing version bump ever happens, and the main thread's save succeeds - so ex is null and the assertion at line 102 fails. The sleep length is irrelevant; the background thread finishes ~2s before the main save. Neo4j keeps equivalent coverage through its own adapted copy, grails.gorm.tests.OptimisticLockingSpec in grails-data-neo4j-core, which commits the session's transaction first. This mirrors the existing Hibernate exclusion on the same feature and the neo4j.gorm.suite gating already used in ValidationSpec for the same "Neo4j requires a transaction" reason. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * test(tck): skip TCK criteria-pagination-without-sort feature for Neo4j Fixing the two TCK gaps under grails-data-neo4j-core:test (this module only started running the shared TCK suite when this PR folded the standalone Neo4j build into the root settings.gradle) surfaced a second one: OptimisticLockingSpec's fix landed separately, this covers PagedResultSpec. "Test that a paged result list is returned from the critera with pagination params" asserts a specific row order from Person.createCriteria().list(offset:1, max:2) { ... } with no explicit sort. Neo4j's criteria query has no implicit ORDER BY, so an unordered page is not guaranteed to come back in insertion order - unlike list(), whose equivalent unsorted-pagination feature passes reliably. Neo4j's own adapted copy of this exact test (grails.gorm.tests.PagedResultSpec in grails-data-neo4j-core) already covers the same scenario with an explicit sort added, with a historical comment noting it was "temporarily disabled due to undefined sorting order" before that fix - direct precedent that this is a known, structural ordering gap rather than new flakiness. Only the criteria-based feature is skipped; the list()-based unsorted pagination feature is left alone since it has no observed failure. Verified: grails-data-neo4j-core:test green 3/3 --rerun-tasks runs (BUILD SUCCESSFUL); TCK report shows skipped=1, 0 failures across all 6 TCK features; Neo4j's own adapted PagedResultSpec still runs both of its features unskipped, 0 failures. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(grails-data-neo4j): BOM-manage neo4j-harness version, dedupe example-app Jetty config Moves the embedded Neo4j 3.5.x test harness version out of the build-internal gradle.properties (and the dead logbackClassicVersion pin alongside it) into grails-neo4j-bom's managed constraints, matching the existing neo4j-driver pattern - fixes generated Forge apps that previously had no managed version for neo4j-harness. Extends the shared neo4j-harness-test-config.gradle to also cover integrationTest classpaths and applies it from all five grails-test-examples/neo4j apps, replacing their independently copy-pasted (and drifted) Jetty-force/allowedBomOverrides blocks with the one shared, correct list. * [skip ci] Release v8.0.0-M4 * [skip ci] Bump version to 8.0.0-SNAPSHOT * Trigger GitHub mergeability recompute (no content change) * test: add more coverage * fix(grails-neo4j-bom): align with 8.0.x derived-BOM pattern Import log4j2-bom ahead of inherited platforms (CVE-2026-49844 ordering, matching every other derived BOM) and apply the shared cli-companion constraints so enforcedPlatform() consumers receive forced companion versions.
