java.lang.ClassNotFoundException: org.apache.gora.hbase.store.HBaseStore

I try to run Nutch 2.0 with HBase as a storage backend for Gora. I following this Tutorial: http://wiki.apache.org/nutch/Nutch2Tutorial and got java.lang.NoClassDefFoundError; this tutorial also covers this error by "copy the lib over from your installed HBase dir into the build lib dir" but I don't know which exactly hbase TEST jar need to copy. If have anyone success run Nutch 2.0 with HBase, please tell me which jar file I need to copy. Thanks you very much. (Sorry about my English writing skill)

This is caused by wrong build configuration. To fix this just open /ivy/ivy.xml and uncomment these lines:

<dependency org="org.apache.gora" name="gora-core" rev="0.4" conf="*->default"/>
<dependency org="org.apache.gora" name="gora-hbase" rev="0.4" conf="*->default" />

And rebuild your nutch with:

ant clean
ant runtime

If it doesn't help then Nutch 2 tutorial says:

It's possible to encounter the following exception: java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/HBaseConfiguration; this is caused by the fact that sometimes the hbase TEST jar is deployed in the lib dir. To resolve this just copy the lib over from your installed HBase dir into the build lib dir. (This issue is currently in progress).

It is not the NoClassDefFoundError from the tutorial. What you miss is gora-hbase-0.2.1.jar. Did you forget to configure gora-hbase dependency in ivy?
