System Documentation

What problem does it solve?

Analyzes JVM projects (Java/Kotlin/Scala/Groovy) and generates knowledge graphs with tree-sitter parsing. Requires Python 3 on the host and a JVM project with Maven/Gradle/Ant/Ivy build files. Skips gracefully if prerequisites are missing. Triggers when asked to "build knowledge graph", "analyze project structure", "parse Java codebase", or "generate dependency graph".

Core Features & Use Cases

  • Detects and analyzes JVM projects (Maven/Gradle/Ant/Ivy) and extracts modules, dependencies, and source structure.
  • Parses Java-based languages (Java/Kotlin/Scala/Groovy) to discover classes, packages, inheritance, interfaces, and annotations.
  • Generates a machine-readable knowledge graph (knowledge-graph.json) for downstream agents or visualization.
  • Use Case: Given a Java monolith with multiple modules, generate a graph showing module dependencies and package structures to guide modernization.

Quick Start

Run python3 scripts/build_knowledge_graph.py /path/to/project /path/to/output to generate knowledge-graph.json.
