Lifecycle Phases

validate → compile → test → package → verify → install → deploy

Useful Commands

bash

mvn dependency:tree                    # View dependencies
mvn dependency:analyze                 # Find unused/undeclared
mvn versions:display-dependency-updates  # Check updates
mvn help:effective-pom                 # View effective POM
mvn -B verify                          # Batch mode build

Troubleshooting

Problem	Solution
Dependency not found	Check repository, version
Version conflict	Use BOM or enforcer
Build OOM	Set MAVEN_OPTS=-Xmx1g
