first question: is this dependency really necessary ? meaning, can you find it somewhere in the hibernate docs ? usually it is in the README in the lib directory of the download.
if we happen to need the lib, did you browse the repository ? i guess it should be there. otherwise i can have it added.
jboss-archive-browsing was required by hibernate-entity manager (specified in the readme of the archive).
I have submitted an updated version of build.properties and dependencies.build.xml to add some libraries (just the required libs to make my tests work with hibernate)
