Distributed Java Programming Build Management  A repeatable build management process allows you to integrate the development efforts of your team often and early.  Traditionally build management has been a combination of manual steps with hard to follow shell scripts.  Because of the cumbersome nature of performing builds, most development teams do not practice any build management.

Distributed Java Programming What is Ant?  ANT is a Java build utility.  Since ANT is Java-based it is platform independent.  ANT is an XML-based tool for automating the various tasks associated with doing a build. These tasks include:  Automated checking out of source code  Incremental compilation of Java source code  File manipulation  Creation of JAR, WAR and EAR files for application deployment  Automated running of unit tests  Launching of various processes needed during build  Generation of Javadocs
