Gora build fails, complains about multiple HBase artifacts

Building with Ant fails for me:

build-common.xml:350: impossible to ivy retrieve: java.lang.RuntimeException: problem during retrieve of org.apache.gora#gora-hbase: java.lang.RuntimeException: Multiple artifacts of the module org.apache.hbase#hbase;0.90.0 are retrieved to the same file! Update the retrieve pattern to fix this error.

Same as the problem here:

So this modification fixes it:

diff --git a/build-common.xml b/build-common.xml
