What java-maven does

This skill guides coding agents through building Java projects with Apache Maven. It supports three layout types: single modules, multi-module setups, and libraries. The agent learns how to navigate phases from validate to deploy, hook build plugins, and structure dependencies.

The skill provides practical recipes for inspecting packages and fixing build issues. When library versions collide, it applies BOM imports or maven-enforcer-plugin. If a build process runs out of memory, it directs the environment to set MAVEN_OPTS=-Xmx1g. The agent relies on Read, Write, Bash, Glob, and Grep access to execute build commands.

What it helps with

Configure pom.xml files for single-module or multi-module Java projects
Pin third-party library versions using dependency BOM imports
Detect undeclared or unused packages via mvn dependency:analyze
Fix build memory exhaustion by configuring MAVEN_OPTS

Example prompts for the agent

Inspect the dependency tree in this repo and check for version conflicts
Set up a pom.xml file targeting Java 21 with Spring Boot BOM dependencies
Run a batch build verification using mvn -B verify
