Show Gradle impact paths only through the modules that resolve a dependency (XRAY-100231)

[Jordanh1996]

Background

Scanning a multi-module Gradle project could abort with a NullPointerException in ImpactTreeBuilder.walkParents, and impact paths could run through modules that exclude the dependency.

Description

With ide-plugins-common 2.5.0 (DepTree.modules()), ImpactTreeBuilder walks each module's own tree and prepends the project root; projects without modules keep the single-tree walk. A vulnerable dependency no walk reaches gets a fallback direct path. Tests load the plugin's Jackson 2.21 ahead of the older copy in the IDE's app.jar.

Tests

New ModuleImpactTreesTest and GradleModuleImpactPathsTest (two modules, one excluding commons-lang3: a single path, through the other), plus a real IntelliJ scan where log4j-core gets one path, through the module that resolves it.

---

• All tests passed. If this feature is not already covered by the tests, I added new tests.

Summary by CodeRabbit

• Bug Fixes
  • Dependency impact paths now reflect the modules that actually resolve each dependency, avoiding attribution to modules that exclude it.
  • Dependencies without a resolving module still receive an impact path.
  • Corrected impact paths for project-root modules to avoid an extra root entry.

📝 Walkthrough

Walkthrough

Impact-tree construction now builds paths from each module’s dependency tree. It handles project-root prefixes and dependencies without a module impact tree. Tests cover module attribution and Gradle fixture behavior.

Changes

Module-aware impact paths

Layer / File(s)	Summary
Build impact paths from module trees src/main/java/com/jfrog/ide/idea/scan/utils/ImpactTreeBuilder.java, src/main/java/com/jfrog/ide/idea/scan/ScannerBase.java	ScannerBase passes the dependency tree to ImpactTreeBuilder. The builder traverses module-specific trees, adds project-root prefixes where applicable, and provides fallback paths for dependencies without an impact tree.
Validate module-specific impact paths src/test/java/com/jfrog/ide/idea/scan/ModuleImpactTreesTest.java, src/test/java/com/jfrog/ide/idea/scan/GradleModuleImpactPathsTest.java, src/test/resources/gradle/moduleImpactPaths/*	Tests cover module-specific resolution, shared dependencies, project-root paths, and dependencies without a resolving module. The Gradle fixture models modules with different transitive dependency resolution.
Update Gradle test classpath setup build.gradle	Dependency versions change, and Gradle Test tasks place Jackson JARs before other classpath entries.

Merge Risk: ⚪ Minimal · up to 4cfd8

Gradle impact paths follow the module that resolves the dependency, while the existing fallback remains for dependencies no module resolves. No material merge-blocking regression is established.
