> I tried to build a UniDic dictionary for using it along with Kuromoji on Solr
> 3.6. I think UniDic is a good dictionary than IPA dictionary, so Kuromoji for
> Lucene/Solr should support UniDic dictionary as standalone Kuromoji does.
> The following is my procedure:
> Modified build.xml under lucene/contrib/analyzers/kuromoji directory and run
> 'ant build-dict', I got the error as the below.
