Update Ant from 1.6.5 to 1.7.1 in Fedora

I have not yet figured out how to install a newer version of Ant across the board yet on my Linux based system. Fedora's repository did not indicate any available packages. I added the JPackage repository and then I was able to see an update for Ant to 1.7.1 which is at least a helpful update over 1.6.5. Yum and Package Manager, however, are both bombing out when I try to install the 1.7.1 version with this error: Missing Dependency: /usr/bin/rebuild-security-providers is needed by package java-1.5.0-gcj
Missing Dependency: lucene = 1.4.3-1jpp.18 is needed by package lucene-devel
