Pros: Nice writing style, clear and not boring, touches not only Ant but quite a few other open-source tools and the Xtreme programming ways... Cons: its vast breath is counterbalanced by
little depth. Ant 's coverage is appropriate to get you started working with it quickly, and to have you appreciate what this tool can do for you. Forget about being able to work with JUnit or XDoclet just by reading this book. You will barely discover that they exist.. and expect a lot of painful hours spent on the traditionally poor open-source docs.
Overall a good buy though. If you want a more in-depth treatment of Ant I recommend Java Development With Ant
