Adding support for Kotlin and mixed Java/Kotlin repositories

Summary by CodeRabbit

  • New Features
    • Added Kotlin source analysis alongside Java, including mixed-language graphs and cycle detection.
    • Added Kotlin metrics and disharmony checks for extensions, sealed hierarchies, and data classes with logic.
    • Added repository-root configuration for accurate multi-module source paths.
    • Added support for anonymous and synthetic classes as graph members.
    • Improved reports and source links for Kotlin, nested, anonymous, synthetic, and duplicate class names.
  • Bug Fixes
    • Improved partial-parse recovery, source mapping, test-directory exclusion, and null handling.
    • Added HTML escaping and collision-safe graph identifiers.
  • Documentation
    • Documented Kotlin analysis requirements, graph behavior, distribution details, and CVE pinning.

Implemented support for Kotlin using GLM-5.2 and Nemotron Ultra
…4 as default language version

- Upgrading rewrite-kotlin version to 8.90.4 and setting Kotlin 2.4 as default language version
- Removed java-rewrite-11 since plugin now requires a Java 17 runtime
… files that aren't part of the Kotlin processing implementation to allow free OSS tooling to work.

sourceFileExtension is plumbed through three files but never read. DependencyVisitorLogic.recordClassLocation derives the file name from sourcePathUri through extractFileNameFromUri, so the extension state and the hooks that feed it describe a synthetic-path behavior that no longer exists.

  • codebase-graph-builder/src/main/java/org/hjug/graphbuilder/visitor/DependencyVisitorState.java#L45-L48: remove the sourceFileExtension field and its accessors, or read it where the synthetic path is built.
  • codebase-graph-builder/src/main/java/org/hjug/graphbuilder/visitor/AbstractDependencyVisitor.java#L42-L42: remove the setSourceFileExtension call and the sourceFileExtension() hook on lines 60-67. Removing the call also removes an overridable-method call from the constructor.

Guard the per-statement log.debug so toString() is not evaluated when debug is off.

The arguments are evaluated eagerly. statement.toString() runs twice for every statement of every Kotlin compilation unit, even when debug logging is disabled. toString() on an OpenRewrite Statement prints the whole subtree, so this allocates the full printed form of each top-level declaration and then discards all but 100 characters.

mergeClassRelationships results are discarded.

merge populates mergedClassRelationships at Lines 134-145. rebuildClassRelationshipsAfterReconciliation then calls mergedClassRelationships.clear() at Line 452 and replaces the contents unconditionally. The two mergeClassRelationships calls therefore have no effect on the returned DTO. Remove the calls and the now-unused mergeClassRelationships helper, or make the rebuild conditional on reconciliation having changed the graph.

Narrow the try block to the Kotlin build.

merge(javaDto, kotlinDto) runs inside the try. A defect in merging, reconciliation, or relationship rebuilding is therefore reported as "Kotlin analysis failed" and silently degrades every mixed-language build to a Java-only graph. Move the merge outside the guarded region so merge defects surface instead of being masked.

CompositeGraphBuilderJavaOnlyTest asserts the opposite of "Java only": Kotlin analysis is unconditional and the analyzeKotlin switch is gone. A name such as CompositeGraphBuilderUnconditionalKotlinTest states the pinned behavior and prevents a reader from looking for a Java-only mode that no longer exists.

Make the package self-edge assertion unconditional.

This test does not cover the package-aware branch it names.

Lines 255-260 build a graph that Line 278 immediately replaces, so that setup is dead. The assertions that remain check the "no package match" case, which duplicates reconcileUnattributedVertices_noPackageMatch_leavesAmbiguousUntouched at Lines 217-238. The package-aware selection branch in CompositeGraphBuilder.reconcileUnattributedVertices (the loop that prefers a candidate whose package equals the fabricated package) stays untested.

That branch is reachable. Construct it with three mapped classes that share a simple name and a fabricated vertex in one of their packages. Example: map com.pkg1.Node, com.pkg2.Node, and com.pkg3.Node; add a fabricated vertex com.pkg2.Node... that FQN is mapped, so instead add the fabricated vertex under a nested package that is also a candidate package, or map com.pkg1.Node and com.pkg2.Node and place the fabricated vertex at com.pkg1.Node only in the graph while the mapping key differs in case. If the branch cannot be reached with a realistic input, remove it from production code instead of keeping an untested path.

Also delete the dead setup at Lines 255-260 and the explanatory comments at Lines 262-277, and rename the test to describe what it asserts.

Strengthen these assertions so they can distinguish the two path modes.

Both tests assert only that the mapped path contains com/example. A repo-root-relative path and a source-root-relative path both satisfy that condition, so neither test would fail if canonicalization regressed. Assert the full expected relative path instead, for example com/example/MyClass.java with assertEquals after normalization, and assert that the path does not start with the absolute temp directory.

to replace “treat is as a Brain Method” with “treat it as a Brain Method” and
change “when expressions unwieldy” to “when expressions become unwieldy.”

Nitpick comments:
In
`@codebase-graph-builder/src/main/java/org/hjug/graphbuilder/CompositeGraphBuilder.java`:
- Around line 134-145: Remove the redundant mergeClassRelationships calls in
merge and delete the now-unused mergeClassRelationships helper, since
rebuildClassRelationshipsAfterReconciliation clears and replaces
mergedClassRelationships unconditionally. Preserve the existing reconciliation
rebuild behavior and returned DTO contents.
- Around line 79-86: Narrow the try/catch in CompositeGraphBuilder so it only
covers KotlinSourceFileGraphBuilder construction and buildGraph; move
merge(javaDto, kotlinDto) after the catch. Preserve Java-only fallback for
Kotlin analysis failures while allowing merge errors to propagate.

In
`@codebase-graph-builder/src/main/java/org/hjug/graphbuilder/metrics/MetricsVisitorLogic.java`:
- Around line 424-433: Extract the duplicated foreign-method signature
construction into a private static buildForeignMethodSignature helper in
MetricsVisitorLogic, preserving the exact declaringFqn.name(paramTypes)
formatting. Update both handleMethodInvocation and handleMemberReference to call
this helper so recordIncomingCall continues matching signatures consistently.

In
`@codebase-graph-builder/src/main/java/org/hjug/graphbuilder/visitor/DependencyVisitorState.java`:
- Around line 45-48: Remove the unused sourceFileExtension state and related
hooks: delete the field/accessors in
codebase-graph-builder/src/main/java/org/hjug/graphbuilder/visitor/DependencyVisitorState.java:45-48,
remove the setter call and sourceFileExtension() hook in
AbstractDependencyVisitor.java:42 and 60-67, and remove the setter call and hook
plus its duplication-only Javadoc in KotlinDependencyVisitor.java:55 and
405-415.

In
`@codebase-graph-builder/src/main/java/org/hjug/graphbuilder/visitor/KotlinDependencyVisitor.java`:
- Around line 88-93: In the per-statement logging logic of
KotlinDependencyVisitor, guard the log.debug call with the logger’s
debug-enabled check so statement.toString() is not evaluated when debug logging
is disabled. Preserve the existing message and 100-character truncation when
debug logging is enabled.

In
`@codebase-graph-builder/src/main/java/org/hjug/graphbuilder/visitor/UnattributedTypeFqnResolver.java`:
- Around line 84-86: Precompile the identifier regular expression as a static
final Pattern in UnattributedTypeFqnResolver, then update the simpleName
validation to use matcher(...).matches() instead of String.matches. Apply the
same change to both identifier-validation locations, preserving the existing
null-return behavior for invalid names.

In
`@codebase-graph-builder/src/test/java/org/hjug/graphbuilder/CompositeGraphBuilderJavaOnlyTest.java`:
- Around line 41-113: Rename the test class CompositeGraphBuilderJavaOnlyTest to
CompositeGraphBuilderUnconditionalKotlinTest so its name reflects the
unconditional Kotlin analysis and removed analyzeKotlin switch asserted by its
tests; update the corresponding class declaration and file name consistently.

In
`@codebase-graph-builder/src/test/java/org/hjug/graphbuilder/CompositeGraphBuilderReconciliationTest.java`:
- Around line 422-426: Update the self-edge assertion in
CompositeGraphBuilderReconciliationTest to unconditionally assert that
mergedPkgEdge is not null before checking its weight, preserving the expected
summed weight of 5.0 for the com.shared self-edge.
- Around line 250-309: Rewrite
reconcileUnattributedVertices_packageAwareMatch_prefersPackageMatch to exercise
the package-preference branch in
CompositeGraphBuilder.reconcileUnattributedVertices with a valid graph and
mapping setup, asserting the candidate whose package matches the fabricated
vertex is selected. Remove the overwritten dead setup and explanatory comments,
and rename the test to describe the behavior it actually verifies; if the branch
is unreachable with valid inputs, remove the untestable production branch
instead.

In
`@codebase-graph-builder/src/test/java/org/hjug/graphbuilder/graphbuilder/KotlinSourceFileGraphBuilderPartialParseTest.java`:
- Around line 29-30: Replace the createTempDirectory/deleteOnExit setup in each
affected test method with JUnit 5’s `@TempDir-managed` temporary directory, adding
the TempDir import and using the injected directory while preserving the
existing test file creation behavior.

In
`@codebase-graph-builder/src/test/java/org/hjug/graphbuilder/GraphBuilderConfigTest.java`:
- Around line 116-124: Strengthen the path assertions in the relevant
GraphBuilderConfigTest cases by normalizing the mapped source path and comparing
it with assertEquals to the complete expected relative path, such as
com/example/MyClass.java. Also assert that the normalized result does not begin
with the absolute temporary-directory path, covering both repository-root and
source-root path modes.

In
`@codebase-graph-builder/src/test/java/org/hjug/graphbuilder/metrics/KotlinPropertyMetricsTest.java`:
- Around line 48-50: Update the file-walking logic in KotlinPropertyMetricsTest
to wrap the Files.walk stream in try-with-resources, while preserving the
existing Kotlin-file filtering and list collection behavior.

📝 Walkthrough

Walkthrough

The change adds mandatory Kotlin source analysis, shared Java/Kotlin visitors, mixed-language graph reconciliation, Kotlin metrics and disharmonies, repository-root source mapping, and Kotlin-aware HTML and cycle reports. It also adds extensive tests and Kotlin fixtures.

Changes

Kotlin analysis and graph construction

Layer / File(s) Summary
Build configuration and public contracts
pom.xml, codebase-graph-builder/pom.xml, codebase-graph-builder/src/main/java/...
Kotlin parsing becomes a managed compile-time dependency. New builder, visitor, configuration, source-mapping, and dependency-collector contracts support Java and Kotlin analysis.
Mixed-language graph construction and reconciliation
codebase-graph-builder/src/main/java/org/hjug/graphbuilder/CompositeGraphBuilder.java, .../graphbuilder/*, .../visitor/*
Java and Kotlin graphs are built, merged, reconciled by class name and package, and rebuilt with preserved edge weights and source mappings.
Shared metrics and Kotlin disharmonies
codebase-graph-builder/src/main/java/org/hjug/graphbuilder/metrics/*
Shared visitor logic collects Java and Kotlin metrics. Metric objects freeze after finalization. Kotlin extensions, sealed hierarchies, data-class logic, callable references, and type bounds are detected.
Kotlin parser and disharmony fixtures
codebase-graph-builder/src/test/resources/kotlin*, codebase-graph-builder/src/test/resources/mixed*, codebase-graph-builder/src/test/resources/parity/*
Fixtures cover Kotlin syntax, mixed-language dependencies, source paths, properties, callable references, type parameters, metrics, and all supported disharmony cases.
Reporting, cycle ranking, and supporting changes
report/src/main/java/..., cost-benefit-calculator/src/main/java/..., graph-algorithms/src/main/java/...
Reports render Kotlin disharmonies and collision-safe DOT identifiers. Cycle ranking consumes merged Kotlin graphs. Supporting POM, formatting, and immutability changes are included.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to 40eed

The Kotlin support changes still contain a reference to an unavailable API that prevents compilation, and an API change may break source consumers; mixed-language metrics also need their repository-wide scope clarified. The PR is not merge-ready until these issues are fixed or explicitly accepted.

Compare Kotlin edges in the parity assertion.

This loop reads only javaGraph. A Kotlin graph with no project edges still passes if it has one vertex. Compare normalized Java and Kotlin edge pairs and weights, or assert the expected Kotlin project edges.

Use J.Import for Kotlin compilation-unit imports.

K.CompilationUnit.getImports() returns J.Import nodes in OpenRewrite 8.90.4. K.Import is not a valid type, so this code does not compile. Replace the loop variable with J.Import.

Collect Kotlin type constraints while the J-method state is active.

K.MethodDeclaration is visited before its wrapped J.MethodDeclaration. At line 141, state.currentMethodMetrics is null. super then enters and leaves the J-method state before this method returns. Kotlin where constraints are not recorded. Move this collection into the J-level method visitor while its snapshot is active. OpenRewrite performs the wrapped J-method visit inside KotlinVisitor.visitMethodDeclaration(K.MethodDeclaration, ...). (raw.githubusercontent.com)

715-715: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Use a collision-free anonymous ID in the graph-aware renderer.

Line 715 returns only <owner>_anonymous, but the renderer calls this overload for vertices and edges. Two active anonymous Kotlin vertices from same-named files in different directories therefore receive the same DOT ID and merge into one report node. Delegate to one collision-free encoder for both overloads. Do not use String.hashCode() as the uniqueness guarantee.

Based on learnings: Anonymous/synthetic classes are first-class graph members.

Preserve the existing public CycleRanker API.

The previous public API included getCodebaseGraphDTO(String, String, boolean, String) and a one-argument constructor. The current class removes the method and generates only a two-argument constructor. Existing consumers can fail to compile. Retain compatibility overloads, or coordinate an explicit breaking release.

@jimbethancourt Yes. Two valid fixes remain in PR #201:

  1. Prevent duplicate Kotlin class-header processing.
    KotlinDependencyVisitor.visitClassDeclaration(K.ClassDeclaration, P) calls DependencyVisitorLogic.enterClassDeclaration after super.visitClassDeclaration. The J-level override already performs that processing during the super traversal. This can increase dependency edge weights for Kotlin class headers. Remove the second K-level enter/leave pair. Add a regression test for a Kotlin class header dependency with an expected edge weight of one.

  2. Update plans/kotlin-implementation-plan-glm-5-2.md.
    The plan still states obsolete design details:

    • OpenRewrite 8.86.0 instead of 8.90.4.
    • Optional rewrite-kotlin support.
    • Reflective KotlinParser probing.
    • An AbstractMetricsCollectingVisitor design instead of MetricsVisitorLogic with MetricsVisitorState.

One active review thread does not require a change. CycleRanker already has the one-argument constructor, and getCodebaseGraphDTO(String, String, boolean, String) did not exist on main or at the PR merge base. That compatibility finding should be withdrawn.

The older owner-state finding is already addressed. visitProperty and visitTypeAlias now use state.getCurrentOwnerFqn().

@jimbethancourt I confirmed both issues. The Kotlin visitor processes each Kotlin class header twice. The implementation plan contains the obsolete design statements.

  • Remove the duplicate Kotlin class-header processing.
  • Add a regression test for the exact Kotlin class-header edge weight.
  • Update the Kotlin implementation plan to describe the current implementation.

@jimbethancourt No additional code fixes are required for PR #201.

Pull requests #203 and #204 have merged into PR #201. They include the previously identified Kotlin class-header fix, regression test, and implementation-plan update.

One active review thread remains. It is invalid. CycleRanker already has the one-argument constructor. getCodebaseGraphDTO(String, String, boolean, String) was not part of the API on main or at the PR merge base. No compatibility overload is required.

@jimbethancourt Yes. The code issues identified in the linked summary have been resolved.

  • The unavailable OpenRewrite API issue was fixed. UnattributedTypeFqnResolver now uses the supported J.ParameterizedType.getTypeParameters() API. The review thread is resolved.
  • The Kotlin class-header duplication issue was fixed in merged PR #204. The regression test requires an edge weight of 1.0.
  • The Kotlin implementation-plan mismatch was fixed in merged PR #204.
  • The anonymous and synthetic class source-path issue was fixed in commits 9629e5b through f5e46fa.
  • The test-source exclusion, Kotlin type-constraint, sealed-hierarchy, and metric immutability issues are resolved.

The CycleRanker compatibility finding was invalid. The one-argument CycleRanker(String) constructor is present. The claimed historical CycleRanker.getCodebaseGraphDTO(String, String, boolean, String) method did not exist on the base branch. No compatibility overload is required.

The linked summary also reported a docstring-coverage warning. I did not verify the current CI result for that separate pre-merge check.
