where problem?? thank much! matteo

since you're running embedded neo4j looks you're missing lucene-core-3.6.2.jar on classpath.

best practice use build system supporting transitive dependencies gradle or maven. easy have dependency on neo4j-community artifact, e.g. http://mvnrepository.com/artifact/org.neo4j/neo4j/2.2.5. pull in other required jars.
