Ant is a Java based build tool, similar to make, but with better support for the cross platform issues involved with developing Java applications. Ant is the build tool of choice for all Java projects at Apache and many other Open Source Java projects.

Changes:
This is the first Ant release that requires at least Java 1.5. It has support for @Ignore annotation and a requirement of JUnit 4.11. The zip, bzip2, and tar are improved. The Perforce Ant tasks have been removed; users of these tasks can use the tasks supplied by Perforce Inc. instead, which contain more functionality and connect natively to the Perforce servers. There are numerous bugfixes and improvements as documented in Bugzilla and in the release notes
