What You Will Learn

• Comprehend the key concepts in Apache Maven
• Build your own custom plugins and get to know how Maven extension points are used
• Troubleshoot build issues with greater confidence
• Optimize Maven's configuration settings
• Write custom lifecycles and extensions
• Get hands-on and create a Maven assembly
• Explore the best practices to design a build system that improves developer productivity

In Detail

Maven is the #1 build tool used by developers and it has been around for more than a decade. Maven stands out among other build tools due to its extremely extensible architecture, which is built on of the concept of convention over configuration. It's widely used by many open source Java projects under Apache Software Foundation, Sourceforge, Google Code, and more.

Maven Essentials is a fast-paced guide to show you the key concepts in Maven and build automation. We get started by introducing you to Maven and exploring its core concepts and architecture. Next, you will learn about and write a Project Object Model (POM) while creating your own Maven project. You will also find out how to create custom archetypes and plugins to establish the most common goals in build automation. After this, you'll get to know how to design the build to prevent any maintenance nightmares, with proper dependency management. We then explore Maven build lifecycles and Maven assemblies. Finally, you will discover how to apply the best practices when designing a build system to improve developer productivity.

Style and approach

This book is a practical and compact guide that will show you how to use Apache Maven in an optimal way to address enterprise build requirements. It provides technical guidance to get you started with Maven and build automation.

Acknowledgments

I would first like to thank Shaon Basu, an acquisition editor at Packt Publishing, who came up with the idea of writing a book on Apache Maven; then, Samantha Gonsalves, a content development editor at Packt Publishing, who I worked with closely throughout the project—thank you very much, Samantha, for your patience and flexibility. Also, I would like to thank all the others at Packt Publishing who helped me to make this book a reality from the initial idea. Thank you very much for all your continuous support.

Dr. Sanjiva Weerawarana, the CEO of WSO2, and Paul Fremantle, the CTO of WSO2, have always been my mentors. I am truly grateful to both Dr. Sanjiva and Paul for everything they have done for me.

If I say she is the driving force behind this book, I am not exaggerating. She simply went beyond by not only feeding me with encouragement, but also by helping immensely in reviewing the book and developing samples. She was always the first r...
