The RAT Antlib already supports working on arbitrary resource
collections, which means you wouldn't even have to download the tarball
yourself if you wanted to.

For RAT's core commons-compress may be a better option, it is more or
less the same code base (for tar, zip and bzip2) and has a lighter
footprint.  Basically you'd have to change a few imports and class names
(TarArchiveInputStream instead of TarInputStream).
