When looking into packaging the Java dependencies talk to the Debian

The Foreman project has nice out of tree packages:
http://deb.theforeman.org/
that are built via a CI system so having a look at their setup might
make sense. If you're using jenkins for CI the jenkins-debian-glue
package might be worth a look.
