I think you just need to tweak build.properties to use the internal 
resolver.

This is what I have symlinked into -common, -hdfs and -mapred

#This is symlinked across projects!
patch.version=1
resolvers=internal
#you can increment this number as you see fit
version=0.22.0-alpha-1
hadoop.version=${version}
hadoop-core.version=${version}
hadoop-hdfs.version=${version}
hadoop-mapred.version=${version}
