My original thought was to attempt to use one of the contrib tasks within an ANT build file. The issue I ran across was the same as adamv points out below: the jar must be placed in ANT's lib folder, but there is no way to tell (that I could find) where the user's ANT install is located. The idea behind this brew is to make this jar available so that other, ANT brews can include the option to install this brew and symlink the jar into their own ANT install.

Do you have any other suggestions?
