ShopCategoriesApp Example
Mike Karrys
I am trying to run the Shop/Categories Example from the Neo4j github
examples and I am getting the following exception. I setup Maven with
the following dependences and everything builds fine but will not run.
Can someone help me resolve this problem?
Thanks, Mike

could you please output the contents of
mvn dependency:tree
? Looks like a version clash ...

I managed to get the database to start by removing the neo4j-utils.jar dependency and commenting out the corresponding code. But now I'm missing those function. They probably are not very hard to recreate if you know what you are doing but I have only been working with Neo4j for a couple of weeks.
I have checkout the neo4j-utils code and changed the POM to neo4j 1.6 but I get this at the end of the compile.

do a
mvn license:format
and see if you can upgrade the project. Pull request afterwards is appreciated!

I figured out how to update the license files but I am still getting a the lucene problem when running the example. My best guess at this point is that It seems to be a version problem between the version of Lucene that the core Neo4j project is using and the version that the neo4j-index project is using. I will see if I can reconcile this.
