You may have read interesting posts on Continuous Integration (CI), Test Driven Development (TDD) or source code and build management process (maybe even on this blog ;)). Most of them show solutions based on Apache Maven tool.
I am not going into details about what Maven is or is not, and how to use it, as Sonatype has released a very good on-line book on the subject "Maven the complete reference", and on top of it it's free. I have read it and I think this book is THE reference to learn Maven or deepen your knowledge on the subject.
Also, take a look Nicolas Frankel's review, a consultant I am working with on a project. I definitely agree with his opinions.
