Java Dependency Scope Classification

Module

Scanner

Status

VERIFIED

Description

Classifies Java dependencies into compile, test, provided, runtime, and system scopes from Maven/Gradle declarations, enabling scope-aware SBOM generation and reachability filtering.

Implementation Details

  • Build Metadata:
    • src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.Java/Internal/BuildMetadata/JavaDependencyDeclaration.cs - Dependency declaration model with scope classification
    • src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.Java/Internal/BuildMetadata/JavaProjectMetadata.cs - Project metadata with declared scopes
  • Maven POM Parsing:
    • src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.Java/Internal/Maven/MavenPomParser.cs - Parses dependency scopes from POM files
    • src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.Java/Internal/Maven/MavenBomImporter.cs - Imports BOM dependencies with scope
  • Gradle Parsing:
    • src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.Java/Internal/Gradle/GradleGroovyParser.cs - Parses compile/test/runtime configurations
    • src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.Java/Internal/Gradle/GradleKotlinParser.cs - Kotlin DSL scope extraction
  • Language Analyzer: src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.Java/JavaLanguageAnalyzer.cs

E2E Test Plan

  • Scan a Maven project and verify dependencies are classified into compile, test, provided, runtime, and system scopes
  • Scan a Gradle project and verify implementation/api/testImplementation/compileOnly configurations map to correct scopes
  • Verify scope information is included in the generated SBOM
  • Verify test-scope dependencies are excluded from reachability analysis by default
  • Verify provided-scope dependencies are correctly handled for runtime vs compile-time analysis
