Decided not to do: compile 'group:name:version' (e.g.  compile 'org.apache.james:apache-mime4j:0.6') to get the dependency from Maven central because:
1) then we need to exclude commons-logging in all of your project's dependencies which transitively depend on commons-logging otherwise we get a lot of warnings at build time
2) also we can't remove the jars from the repo as long as we support ant
