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.

Inline comments:
In `@codebase-graph-builder/pom.xml`:
- Around line 61-69: Remove the explicit version from the rewrite-kotlin
dependency, allowing rewrite-recipe-bom and its imported rewrite-bom to manage
it consistently with rewrite-core.
In
`@codebase-graph-builder/src/main/java/org/hjug/graphbuilder/CompositeGraphBuilder.java`:
- Around line 217-250: Update the reconciliation flow around
reconcileUnattributedVertices so anonymous-class vertices generated from
attributed J.NewClass types, such as Outer$1, are mapped to their enclosing
source path before candidate matching and pruning. Ensure
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.
In
`@codebase-graph-builder/src/main/java/org/hjug/graphbuilder/graphbuilder/KotlinSourceFileGraphBuilder.java`:
- Around line 77-88: Update KotlinSourceFileGraphBuilder and
JavaSourceFileGraphBuilder so the test-source exclusion filter is applied only
when excludeTests is true and testSourceDirectory is non-null and non-empty;
otherwise retain all supported source files. Consolidate each builder’s
duplicated .kt/.kts or Java extension filtering into a shared stream path while
preserving CompositeGraphBuilder behavior.
In
`@codebase-graph-builder/src/main/java/org/hjug/graphbuilder/metrics/GraphMetricsCollector.java`:
- Around line 291-314: Update computeSealedDepth to traverse sealed ancestors
before treating a class as a root: retain depth 1 only when no sealed hierarchy
ancestor exists, otherwise derive the maximum ancestor depth plus one. For
ancestors absent from classMetrics, preserve a minimum depth of 2 instead of
continuing to a zero result, and add coverage for a sealed subclass and a
partial parse.
In
`@codebase-graph-builder/src/main/java/org/hjug/graphbuilder/metrics/KotlinMetricsCollectingVisitor.java`:
- Around line 139-149: Update visitMethodDeclaration so Kotlin type constraints
are collected before super.visitMethodDeclaration, while
state.currentMethodMetrics still refers to the method being visited; preserve
the existing null checks and MetricsVisitorLogic.collectTypeParameterFqns call,
and avoid recording constraints after the superclass traversal restores the
enclosing method state.
- Around line 261-267: Update isOverrideAnnotation to recognize only the Java
Override annotation, removing the JvmOverride branch. Also delete the related
Javadoc claim about JvmOverride while preserving Kotlin modifier handling
through hasKotlinOverrideModifier.
In
`@codebase-graph-builder/src/main/java/org/hjug/graphbuilder/metrics/MethodMetrics.java`:
- Around line 113-116: Update MethodMetrics.setNormalizedBodyLines to store a
defensive copy of the provided list, then invalidate normalizedBodyLinesView so
getNormalizedBodyLines rebuilds its view from the replacement data. Preserve the
existing requireMutable guard.
- Line 18: In MethodMetrics, suppress Lombok-generated setters for finalized,
numberOfCallableReferences, and mutable collection fields, then provide explicit
replacement setters that call requireMutable() where needed. Update
setNormalizedBodyLines(...) to copy the incoming list and rebuild its cached
view whenever the list is replaced, preserving freeze() protections and
preventing external mutation.

since restoration now uses the per-class snapshot.
In
`@codebase-graph-builder/src/main/java/org/hjug/graphbuilder/visitor/KotlinDependencyVisitor.java`:
- Line 40: Update visitProperty and visitTypeAlias to gate on the shared
state.currentOwnerFqn instead of the duplicate currentOwnerFqn field, then
remove that field and its previousOwner save/restore and assignment from
visitClassDeclaration(K.ClassDeclaration, P) while retaining owningFqn for
type-constraint processing. Ensure the shared owner-state nested-class handling
is corrected in DependencyVisitorLogic as required so ownership remains valid
across nested classes.
In
`@codebase-graph-builder/src/main/java/org/hjug/graphbuilder/visitor/UnattributedTypeFqnResolver.java`:
- Around line 113-146: Update resolveParameterizedType to obtain parameters via
pt.getTypeParameters(), filter the returned Expression values to TypeTree, and
collect them into the existing typeArguments array. Remove the reflective lookup
and its reflection imports, adding the required Collectors import while
preserving the existing null/empty handling.
In
`@codebase-graph-builder/src/test/java/org/hjug/graphbuilder/metrics/KotlinDisharmonyTest.java`:
- Around line 61-63: Update the file-discovery logic in KotlinDisharmonyTest to
wrap the Files.walk stream in try-with-resources, ensuring it closes after
collecting Kotlin paths while preserving the existing filtering and collection
behavior.
In `@plans/kotlin-implementation-plan-glm-5-2.md`:
- Around line 149-155: Update plans/kotlin-implementation-plan-glm-5-2.md at
lines 149-155 to make Kotlin analysis mandatory, require the rewrite-kotlin
dependency, and specify direct KotlinParser selection instead of reflective
probing; update lines 31-33 to use OpenRewrite Kotlin and BOM version 8.90.4;
update lines 74-75 to document composition via static MetricsVisitorLogic
helpers and MetricsVisitorState, noting that JavaIsoVisitor and KotlinIsoVisitor
cannot share an abstract base.
Apply the same fix in `@plans/kotlin-implementation-plan-glm-5-2.md` at line 66.
In `@pom.xml`:
- Around line 355-376: Update the rewrite-maven-plugin exclusions in its
configuration to also exclude Kotlin parser fixture trees under
kotlin*SrcDirectory and mixedSrcDirectory patterns, while preserving the
existing testclasses exclusion. Ensure rewrite:run cannot modify these
plain-text test resources.
In `@report/src/main/java/org/hjug/refactorfirst/report/HtmlReport.java`:
- Around line 666-673: Update both anonymous-node ID paths in renderSafeNodeId
to append a deterministic discriminator derived from the full vertex FQN,
ensuring anonymous classes from same-named files and normal classes cannot
collide; retain the source-file base name only for display labels. Add a
regression test covering anonymous vertices from same-named files in different
packages and verifying distinct rendered IDs.
In `@report/src/main/java/org/hjug/refactorfirst/report/SimpleHtmlReport.java`:
- Around line 294-315: Update the remediation text in the DisharmonySpec entries
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.”

🌐 Web query:
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].

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
attributed J.NewClass types, such as Outer$1, are mapped to their enclosing
source path before candidate matching and pruning. Ensure
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.

Do not process Kotlin class headers twice.
super.visitClassDeclaration(classDeclaration, p) visits the wrapped J.ClassDeclaration, and the J-level override already calls DependencyVisitorLogic.enterClassDeclaration. The K-level method calls it again for the same jcd, so GraphDependencyCollector increments repeated header dependency weights.
Remove the K-level enterClassDeclaration call. Keep the J-level entry path and process only Kotlin-specific type constraints with owningFqn.
