Ant in Action is divided into three parts. Part 1 introduces the fundamentals of Ant and shows how to use it to build, test, package, and deliver a Java library. Part 2 takes what you learnt in Part 1 further, and explores how to use Ant to solve specific problems, like coordinating a multi-project build, and deploying and testing web and Enterprise applications. Part 3 which will be very useful for experienced Ant users, is a detailed guide on how to extend Ant in scripting languages and Java code.
