If you prefer the source edition, you can download the source for the latest Ant release from http://ant.apache.org/srcdownload.cgi. Again, if you prefer the edge, you can access the code as it is being developed via CVS. The Jakarta website has details on accessing CVS. Please checkout the ant module. See the section Building Ant on how to build Ant from the source code. You can also access the Ant CVS repository on-line.
