Hello,
Over the last couple of months have been experimenting with Gora as a
storage layer for Nutch 2.0 and to date have experienced no real problems
that I thought justified a shout on the dev list, however I'm left
scratching my head here. The list archive doesn't seem to show anyone else
struggling so I'm guessing it's my lack of knowledge of the Gora code base
which is restricting me.
I just checked out the trunk today and upon compiling the code I'm getting a
rather nasty error as follows
BUILD FAILED
/home/lewis/ASF/gora/build.xml:272: The following error occurred while
executing this line:

Looking closer I can see that the <dependency org="org.apache.cassandra"
name="cassandra-thrift" rev="0.8.1"/> exists in
$GORA_HOME/gora-cassandra/ivy/ivy.xml, however what I am puzzled at is from
where else the artefact retrieval is being duplicated?
thank you for any pointers.
