As best I can tell, the jpackage repository hasn't received any updated
packages since October 2009. For that reason, I recommend it be removed
from opscode cookbooks. Please correct me if I am mistaken about the status
of the jpackage repository.
There are versions of tomcat and ant available in the main centos and rhel
repositories. Unfortunately, there do not appear to be rpms available for
maven or jetty.
I think the best strategy would be to remove the jpackage cookbook and
refactor the jetty and maven cookbooks so they download the binaries
directly from the project website,
I have already done this w/ my installer for maven
