lucene versions conflict in lucene-lda and solr

[jianleiusc]

The lucene version in lucene-lda is lucene-core-3.0.2, However in solr the lucene version: lucene-core-5.3.1.

So I replace lucene-core-3.0.2 with lucene-core-5.3.1, then build an install lucene-lda. then run bin/indexDirectory test outInde outLDAInde, and I got the following error:
