About the Authors
Maria Odea Ching grew up in Daet, a small town in the Philippines, then moved to the country's capital, Manila, when she went to college. She took up Computer Studies at De La Salle University, and graduated in 2004. She started using open source tools from her first job after graduating. From then on, she got interested in the open source philosophy. She was introduced to Apache Maven, Apache Continuum, and Apache Archiva early on in her career. She became a committer and a Project Management Committee member of Apache Maven. Eventually, she was elected as PMC Chair of Apache Archiva. She is also a member of the Apache Software Foundation.
Deng is currently a Senior Software Engineer and serves as the development lead for the Maestro project.
First, I'd like to thank Brett for the whirlwind endeavor which is this book. I'd also like to thank all our reviewers—Wendy, Emmanuel, Carsten and the Packt team, for taking the time to review and go through each chapter. You guys rock! And of course without the communities of Maven, Continuum, and Archiva, we wouldn't have anything to write about. So I'd like to thank each and everyone (committers/developers, contributors, buggers) in these respective communities. I'd also like to give special thanks to our Exist/G2iX family for their continuous support.
And last but definitely not the least, I'd like to thank my family and my boyfriend, Mike, for their unfaltering love and support and for being so patient and understanding when I have to run off to work on the book.
Brett Porter is a software developer from Sydney, Australia with a passion for development tooling and automation. Seeking a more standardized and reproducible solution to organize, build, and deploy a number of software projects across teams, he discovered an early beta of Maven 1.0 in 2003, and has been heavily involved in the development of the project since. He is a member of the Apache Maven Project Management Committee, and has conducted presentations and training on Maven and related tooling at several conferences and events. He founded the Archiva project in 2005. Brett is also a Director and Member of the Apache Software Foundation.
Brett is currently VP, Product Development at G2iX, in charge of the MaestroDev division. He and his team seek to make developers more efficient by offering support and services for development and automation tools including Apache Maven, Apache Continuum, Apache Archiva, and Selenium.
Brett was co-author of the book Better Builds with Maven, the first book to be written about the Maven 2.0 release in 2005, and has been involved in reviewing Maven: ADeveloper's Notebook and Java Power Tools.
I'd first like to thank my co-author and friend Deng for agreeing to participate in this book and lending her experience with Archiva and Continuum. I am grateful to all of the reviewers that volunteered their time to help make this the best that it can be. My great thanks go to all the members of the open source community that participate in these projects—the developers, as well as those that contribute patches, detailed bug reports, or answer questions on the user lists—not only do we build great software together, but I get the chance to work with truly remarkable individuals.
Finally, my love and thanks go to my wife Laura for sparing some more of our precious time so that I could complete this book, and for supporting me in everything I do.

Preface
This book offers a comprehensive look at using Maven on a project, covering not only the build system itself, but how it is best used in concert with other development infrastructures such as source control, continuous integration and build servers, and an artifact repository. We cover this territory using Subversion, Apache Continuum, and Apache Archiva, respectively, though the concepts learned should apply to other comparable systems.
In many ways, this is the book we've always wanted to write about Maven, and it takes a different approach to the existing Maven titles. Rather than being a reference or documentation for the software, it takes the approach of walking through a single example application and associated infrastructure in the same way that you would develop your own projects. For this purpose, we have crafted the example application Centrepoint—a simple but functional web application composed of several modules that itself interacts with Maven, Continuum, and Archiva.
We believe this book will not only show you how to use Maven, but how to use it effectively, covering concepts and best practices that should endure beyond the current versions of Maven and apply to your development infrastructure and teams in general.
What this book covers
Chapter 1: Maven in a Nutshell is a quick overview of the fundamentals of Maven—from creating a simple Maven project to basic plugin configuration to generating sites and reports. These are demonstrated in an easy to follow step-by-step process. By the end of the chapter, you should be able to apply and use the skills that you have learned to your own project.
Chapter 2: Staying in Control with Archiva introduces you to Archiva and its role in building software. You will learn the basics of installing and configuring it for internal use. It also shows you how Archiva complements Maven and how they can be used together efficiently.
Chapter 3: Building an Application Using Maven delves into the details on how to accurately set up and build an application using Maven. The Centrepoint project is introduced in this chapter. This is the sample application that will be used for the hands-on demonstrations throughout the book. You will see how Maven enforces convention over configuration while building the Centrepoint project.
Chapter 4: Application Testing with Maven goes through the various types of automated tests that can be executed from Maven. This includes unit testing, integration testing, and testing web applications using Selenium to name a few. Instrumenting tests, implementing test coverage, and reporting of test results are also covered.
Chapter 5: Reporting and Checks shows how to configure Maven to generate project reports and incorporate them in the generated site. This chapter also tackles the basics on enforcing certain rules or checks on your code such as conforming to code styles and standards, and finding common bugs in the code while building your application.
Chapter 6: Useful Maven Plugins discusses some of the Maven plugins, both from Apache Maven and from the Codehaus Mojo project, that may be of great help in your Maven builds. The functionality of these plugins range from keeping track of the source revision number for the build to executing external applications as part of the build. You will learn to identify when to use each plugin and how to configure them properly to address your need.
Chapter 7: Maven Best Practices illustrates the effective usage of Maven. You will learn tips and tricks for setting up your development environment to managing your project dependencies to making your builds portable and reproducible. By the end of this chapter, you should be able to apply what you've learned to your next project, or even to your current one.
Chapter 8: Continuum: Ensuring the health of your source code highlights the importance of continuous integration in software development through Continuum. It covers basic installation and set up, adding projects to Continuum, and effective configuration and build scheduling, at the same time demonstrating how it works in accordance with Maven and also with Archiva.
Chapter 9: Continuum in Depth deals with releasing projects using both Maven and Continuum. The different phases involved in the release process will be covered along with a bit of troubleshooting on the side. You will also learn about building multiple projects simultaneously in Continuum through parallel and distributed builds.
Chapter 10: Archiva in a Team gives you the more advanced features of Archiva and demonstrates how to configure it for use in a team. You will learn how to control access to a repository, how to take advantage of repository groups, how to make use of its reporting feature, and how to maintain your Archiva repositories.
Chapter 11: Archetypes covers Maven archetypes. It discusses some of the archetypes available—what their purpose is and what the generated project from each archetype looks like. You will also create a custom archetype specifically for the Centrepoint application, which will be used in the last chapter.
Chapter 12: Maven, Archiva, and Continuum in the Enterprise shows how to configure Archiva and Continuum effectively for use in the corporate environment. Tips on how to set up projects and repositories across multiple projects with respect to controlling who and what can be accessed by different teams covers the first half of the chapter. The second part demonstrates the web services feature of both applications by creating plugins for the Centrepoint application and using them to get information from Archiva and Continuum.
Appendix A: Troubleshooting Maven provides techniques for troubleshooting Maven. Incorrect POM or settings configuration, and dependency and download problems are a few of the usual suspects that will be covered here.
Appendix B: Recent Maven Features discusses the new features in Maven 2.1 and above. These features include password encryption, reactor project selection, and parallel downloads of dependencies.
Appendix C: Migrating Archiva and Continuum Data illustrates how to migrate data in Archiva and Continuum when upgrading to a higher version. How to switch to a different database from the built-in one is also discussed.
