Apache Maven Training — Modern Java Build Automation & Dependency Management

What Is Apache Maven?

Apache Maven is the most widely used build automation and dependency management tool for Java projects. Based on the Project Object Model (POM), Maven provides a standardized build lifecycle — compile, test, package, deploy — with declarative configuration and a vast plugin ecosystem. Maven is the build backbone of most enterprise Java applications and a fundamental skill for Java DevOps engineers.

Where Maven Fits in Modern DevOps

Maven is a first-class citizen in modern CI/CD. Every major CI platform (Jenkins, GitHub Actions, GitLab CI, Azure DevOps) has native Maven support. Maven integrates with artifact repositories (Nexus, Artifactory), code quality tools (SonarQube), test frameworks, and container builds. Understanding Maven deeply — not just running mvn clean install — is essential for Java delivery pipeline engineering.

Who Should Attend

• Java developers who want to move beyond basic Maven usage
• DevOps engineers building CI/CD pipelines for Java applications
• Build/release engineers managing multi-module enterprise builds
• Teams migrating from Ant to Maven

Learning Outcomes

• Configure Maven POM files for single and multi-module projects
• Manage dependencies, transitive dependencies, and version conflicts
• Build custom Maven plugins and use the plugin ecosystem effectively
• Integrate Maven with Nexus/Artifactory for artifact management
• Run Maven builds in Jenkins, GitHub Actions, and GitLab CI pipelines
• Implement code quality (Checkstyle, SpotBugs) and coverage (JaCoCo) in Maven builds

Course Modules

1. Maven Fundamentals — Convention over configuration. Build lifecycle. POM structure. Coordinates (GAV).
2. Dependency Management — Scopes. Transitive dependencies. Dependency mediation. BOMs. Version ranges.
3. Multi-Module Builds — Parent POM. Module aggregation. Inheritance vs. composition. Reactor build order.
4. Maven Plugins — Core plugins. Plugin goals. Plugin configuration. Writing custom plugins (Mojo).
5. Testing & Quality in Maven — Surefire, Failsafe. JUnit 5. Checkstyle, SpotBugs, PMD. JaCoCo coverage.
6. Artifact Management — Nexus/Artifactory integration. Snapshot vs. release repos. Deployment. Promotion.
7. Maven in CI/CD — Jenkins pipeline (Jenkinsfile) with Maven. GitHub Actions with Maven. Caching. Parallel builds.
8. Maven Release Process — Maven Release Plugin. Versioning strategies. Preparing and performing releases.
9. Maven Best Practices — Bill of Materials (BOM). Enforcer plugin. Dependency convergence. Repository management.
10. Capstone: Enterprise Maven Build — Set up a multi-module Maven project with CI/CD, artifact management, quality gates, and release automation.

Hands-on Exercises

Create multi-module Maven projects. Configure dependency management with BOMs. Write custom Maven plugins. Integrate SonarQube and JaCoCo. Build a complete Jenkins pipeline for a Maven project with artifact deployment to Nexus.

Enterprise Use Cases

• Managing 50+ module Java applications with consistent dependency versions
• Building Java microservices with standardized Maven archetypes
• Integrating Maven builds with Sonatype Nexus for artifact lifecycle management
