Search M2 Agent Skill

Search for Java classes inside Maven dependencies in ~/.m2. Use when the user asks to locate classes or inspect JARs. Cross-reference pom.xml files in the current directory to resolve dependency names/versions.

Search Maven Local Repository (search-m2)

Use this skill to find which dependency JAR contains a class and to inspect JAR contents in ~/.m2/repository.

Preconditions

Work from the user’s current directory.
Look for pom.xml files in the current directory tree and use them to resolve dependency names and versions.

Key paths

Maven local repo: ~/.m2/repository
Dependency JAR path pattern:

~/.m2/repository/<groupId path>/<artifactId>/<version>/<artifactId>-<version>.jar

Steps

Discover pom files: run find . -name pom.xml from the current directory.
If multiple poms exist, prefer the closest one to the current directory or ask the user which project/module to use.
Extract dependency coordinates:
If the user provides a group/artifact, search the poms for that dependency and read its version.
If versions are defined via properties (e.g., ${foo.version}), resolve the property from the same pom (or parent if obvious).
Resolve the JAR path using the groupId/artifactId/version mapping above.
If the version is not found, list available versions in ~/.m2/repository/<groupId path>/<artifactId>/ and ask the user which to inspect.
Search for classes:
List classes: jar tf <jar> | rg '\.class$'
Find a specific class: jar tf <jar> | rg '<ClassName>(\.class)?$'
Inspect class details (if requested):
javap -classpath <jar> <fully.qualified.ClassName>

Useful commands

Find a class across all jars (fallback)

rg -g '*.jar' --files ~/.m2/repository | while read -r jar; do
  jar tf "$jar" | rg -q 'com/example/MyClass.class' && echo "$jar"
done

Resolve versions for a dependency

ls ~/.m2/repository/<groupId path>/<artifactId>/

Notes

If the user is vague, start by identifying the relevant pom.xml and extracting dependency coordinates.
If the dependency is transitive and not in the pom, check mvn -q -DskipTests dependency:tree (only if needed and the user agrees).
