• Configure Maven POM files
• Manage dependencies with BOMs
• Set up build plugins
• Create multi-module projects
• Troubleshoot build issues

Quick Reference

<project xmlns="http://maven.apache.org/POM/4.0.0">

    <groupId>com.example</groupId>
    <artifactId>my-app</artifactId>
    <version>1.0.0-SNAPSHOT</version>

        <java.version>21</java.version>
        <maven.compiler.source>${java.version}</maven.compiler.source>
        <maven.compiler.target>${java.version}</maven.compiler.target>

            </dependency>
        </dependencies>
    </dependencyManagement>

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-enforcer-plugin</artifactId>
                <version>3.4.1</version>
            </plugin>
        </plugins>
    </build>
</project>

Lifecycle Phases

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

Useful Commands

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
