Adding support for Kotlin and mixed Java/Kotlin repositories

Summary by CodeRabbit

  • New Features

    • Added Kotlin source analysis alongside Java, including mixed-language dependency graphs and cycle detection.
    • Added Kotlin metrics and disharmony checks for excessive extensions, large sealed hierarchies, and data classes containing logic.
    • Improved source links and DOT graph rendering for Kotlin, anonymous, synthetic, nested, and duplicate-named classes.
    • Added multi-module project support with repository-root-relative source paths.
    • Kotlin files are now included in change-proneness analysis.
  • Bug Fixes

    • Reports now safely escape class names and handle missing source mappings without broken links or errors.
    • Anonymous and synthetic classes are represented consistently in graphs and reports.

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.

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.

Remove the explicit rewrite-kotlin version.

rewrite-recipe-bom 3.37.0 imports rewrite-bom 8.89.0, which manages rewrite-core and rewrite-kotlin at 8.89.0. The explicit 8.90.4 version creates mixed OpenRewrite versions and can cause binary-linkage errors during Kotlin parsing.

OpenRewrite J.NewClass getType anonymous class JavaType.FullyQualified anonymous FQN

💡 Result:

In OpenRewrite, anonymous classes are represented using the JavaType.FullyQualified hierarchy, typically as a JavaType.Class instance [1][2]. When you encounter a J.NewClass AST element that represents the instantiation of an anonymous class, its type (retrieved via getType or indirectly via the class type) corresponds to a JavaType.FullyQualified implementation [3][1]. Key details regarding the anonymous class FQN in OpenRewrite include: 1. Fully Qualified Name (FQN) Structure: OpenRewrite follows the Java Virtual Machine naming convention for anonymous classes, which typically uses the format OuterClassName$1, OuterClassName$2, and so on [4]. 2. JavaType.FullyQualified: This interface is the base for all classes, including anonymous ones [1]. It provides the getFullyQualifiedName method, which will return the internal representation (e.g., "com.example.Outer$1") [5][1]. 3. Handling Anonymous Classes: While J.NewClass holds the constructor information, the anonymous class body is represented by the body field within J.NewClass, and its associated type information is stored as a JavaType.FullyQualified [3][6]. Because anonymous classes do not have user-defined names, their FQNs are generated by the compiler and may change if the code is recompiled, which is a known challenge when performing refactoring operations like substitution [4]. To inspect the type of a J.NewClass, you typically call getType if the node is attributed, or inspect the constructor type if you are looking for specific instantiation details [3][7]. For structural analysis, always verify the instance is a JavaType.FullyQualified before calling getFullyQualifiedName [1].

Map Java anonymous-class vertices before reconciliation

When AbstractDependencyVisitor.visitNewClass processes an attributed anonymous class, J.NewClass.getType() can produce a generated FQN such as Outer$1. GraphDependencyCollector.addClassDependency adds that FQN as a vertex, but no recordClassLocation call maps it. If no mapped class has the same simple name, reconcileUnattributedVertices treats it as external and removeFabricatedExternalVertex deletes the vertex and its edges. Add source-path mappings for these vertices before reconciliation, or exclude known source vertices from external pruning.

reconcileUnattributedVertices so anonymous-class vertices generated from

GraphDependencyCollector-added vertices with known source origins are not passed
to removeFabricatedExternalVertex merely because no simple-name candidate
exists, while preserving external-class removal for genuinely unmapped vertices.

Guard the test-source filter in both builders.

When excludeTests is true and testSourceDirectory is "", String.contains("") matches every path. Both KotlinSourceFileGraphBuilder and JavaSourceFileGraphBuilder then exclude all supported source files. CompositeGraphBuilder.getCodebaseGraphDTO(..., true, "") passes these values into both builders. Guard empty and null values, and consolidate the duplicated extension filter in each builder.

Correct sealed-hierarchy depth traversal.

Line 292 returns depth 1 for every sealed class. A sealed subclass must inherit its sealed ancestor depth. Lines 304-308 also specify a depth-2 fallback for an ancestor outside the parse batch, but the continue returns 0.

Resolve ancestors before classifying a class as a root. Preserve a depth of at least 2 for a recorded external sealed ancestor. Add coverage for a sealed subclass and a partial parse.

Record Kotlin type constraints before the inner method traversal.

super.visitMethodDeclaration(methodDeclaration, ctx) visits the wrapped J.MethodDeclaration. The J-level visitor then calls leaveMethod, which restores the previous state.currentMethodMetrics. The code at line 142 therefore drops the Kotlin where constraints or records them on the enclosing method. This breaks the method-level typeParameterFqns contract exercised by KotlinMetricsCollectionTest. Collect the constraints in the J-level visitor while the method state is active, or capture them before the super call.

Close the Files.walk stream.

Files.walk keeps directory handles open until its stream closes. This loader runs for each test, so retained handles can cause file-lock failures on supported platforms. Use try-with-resources.

2. **Optional Maven dependency** — `rewrite-kotlin` marked `<optional>true</optional>`
3. **Kotlin language level**: `KOTLIN_2_2` (parser default), configurable via `GraphBuilderConfig`
4. **Kotlin disharmonies as ClassDisharmony** — reuses existing downstream plumbing
5. **Callable references & type parameters feed BOTH graph edges AND metrics** No newline at end of file

The Kotlin parser fixtures under codebase-graph-builder/src/test/resources/kotlin*SrcDirectory/** and **/mixedSrcDirectory*/** are deliberate plain-text inputs whose exact shape drives the metric assertions. A rewrite run would modify them and change test outcomes.

Add the fixture trees to <exclusions>.

🛡️ Proposed fix
                     <exclusions>
                         <exclusion>**/testclasses/**</exclusion>
+                        <exclusion>**/src/test/resources/**</exclusion>
                     </exclusions>

Make source-aware anonymous node IDs collision-free.

Lines 669-670 and 707-710 derive the node ID only from the source file base name. For example, a.Foo.<anonymous> mapped to a/Foo.kt and b.Foo.<anonymous> mapped to b/Foo.kt both render as Foo_anonymous. A normal class named Foo_anonymous also collides.

DOT treats these as one vertex. This merges edges and source URLs, so the Class Map and Cycle Map can show false relationships. Add an FQN-derived unique discriminator to the anonymous node ID. Keep the source-file base name only in the display label. Add a regression test with two anonymous vertices from same-named files in different packages.

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

Also applies to: 701-717

Correct the new remediation text.

Change “treat is as a Brain Method” to “treat it as a Brain Method.” Change “when expressions unwieldy” to “when expressions become unwieldy.”
