Subject Re: CouchDB-Lucene, getting it running
Date Wed, 20 Jan 2010 01:06:31 GMT
Patrick,


It works! I assumed i already used Sun's JRE so i didn't pay much
attention to the note in the readme, how silly. It seems that gij was
installed, and it took over /etc/alternatives and even kept working after
a `thorough` apt-get purge!


After linking /etc/alternatives/java to
/usr/lib/jvm/sun-java-6/jre/bin/java Maven finally didn't complain.
Perhaps mentioning this conflict in the readme would be a good idea, it
surely cost me quite some time.


Cheers,
