I got the same error when trying to use only the source code from github in eclipse and running some neo4j example, i eventually ended up using the precompiled jars which fixed the problem(and I had them point to the source code to see the javadoc), but I would really love to use the latest sources from github, and this same error is preventing me to do so: No index provider 'lucene' found
