building-java-knowledge-graph

Prerequisites

Step 1 — Verify JVM project:

find "$PROJECT_ROOT" -maxdepth 5 -type f \( -name "*.java" -o -name "*.kt" -o -name "*.scala" -o -name "*.groovy" \) | head -1

If no JVM files found: skip this skill. Set knowledge_graph_dir to null in setup_artifacts. Non-fatal — downstream agents fall back to direct source analysis.

Step 2 — Verify Python:

python3 --version 2>/dev/null || python --version 2>/dev/null

If unavailable: skip this skill with same fallback as above.
