ElasticSearch and Neo4j Compatibility Issue

I am developing a Question answering application and for that I need to use neo4j and elasticsearch in the same maven project. I am using elasticsearch to make my application more robust.
As we know that neo4j and elasticsearch works on different version of lucene, so whichever version I include in dependency, it gives an error.

Is there any way that I can integrate neo4j and elasticsearch in same maven project, or is there any other way through which these two modules can interact separately.The method that is given on http://neo4j.com/developer/elastic-search/ will not work for me since I am using the default java driver.
