There are a couple of issues with ant now. The main issue is that the dependencies have been
removed from the source tree, which is a good thing. However it means that you will have to
get them yourself. See my mail on the mailing list on how to do that using maven. The debug
server is broken now because the mysql libraries are not copied to the lib directory anymore
because that lib is also gone. Put it in the webapp lib folder and everything should work,
but I did not test this.

Good point, I've consolidated some info that was posted to the dev list and updated the wiki
page here: https://cwiki.apache.org/confluence/display/CLOUDSTACK/Building+with+Maven

See the thread "[DISCUSS] Build process/binaries in our tree/candidate to begin testing with"
for the how and why of this change. I agree it's a pita now, but hopefully it means we can
ship version 4.0.0 when we fix this.
