Implementation Status

Completed

classpath.py — Maven classpath resolution cached in target/java-nav/classpath.txt
classpath.py — Per-JAR dependency source extraction (finds -sources.jar in ~/.m2/, extracts only what's needed)
classpath.py — find_source_roots() auto-discovers source dirs in multi-module Maven projects
api — javap wrapper (-public/-protected/-private), clear error on class not found
source — locate source from project or deps, line ranges (-l), javap fallback when no source JAR
grep — ripgrep/grep with --deps and --test, multi-module aware, helpful "no matches" message with hints
deps — jdeps wrapper with --package, searches submodule target/classes/ too

ClassGraph scanner JAR (tools/classgraph-scanner/ → src/java_nav/jars/classgraph-scanner.jar)
impls — find all implementations of an interface
subtypes — find all subclasses

lsp start/stop/status — persistent jdtls daemon with PID+port file management
refs — find all references, text-based input (Class.method), resolves to position internally
def — go to definition, shows source context around definition
find — semantic workspace symbol search (classes, interfaces, enums)
symbols — document symbols with line numbers and kinds
On-demand mode (no daemon, ~5-15s per query) + daemon mode (<200ms per query)

install-skill — writes .claude/skills/java-nav/SKILL.md with strict agent rules
Playground test fixture (Repository × 2 impls, AbstractProcessor × 2 subtypes, UserService + Guava)
spring-petclinic integration tests (12 tests via git submodule)
LSP integration tests (8 tests against playground)
ruff lint + format (E, W, F, I, UP, B, SIM)
pytest with integration marker separation (26 unit + 20 integration)
Agent-friendly error messages on all commands (no silent failures)
Multi-module Maven support (grep, source, deps)
