Is module missing a library, if so which one?

It seems that the module for Neo4j is missing the neo4j-cypher-2.0.1.jar: http://m2.neo4j.org/content/repositories/releases/org/neo4j/neo4j-cypher/2.0.1/neo4j-cypher-2.0.1.jar

I'm going to fix this but in the meanwhile you can include the library in:
<jboss_home>/module/org/hibernate/ogm/neo4j/main

and update the module/org/hibernate/ogm/neo4j/main/module.xml
adding:

Code:

<resource-root path="neo4j-cypher-2.0.1.jar" />

Sorry for the inconvinience,
Davide

Hi again, and many thanks for your guick reply. Adding neo4j-cypher-2.0.1.jar did not help but it set me to the correct path final result looks like this:

neo4j:main module.xml

Code:

<resource-root path="neo4j-cypher-2.0.1.jar" />
<resource-root path="neo4j-cypher-commons-2.0.1.jar" />
<resource-root path="neo4j-cypher-compiler-1.9-2.0.1.jar" />
<resource-root path="neo4j-cypher-compiler-2.0-2.0.1.jar" />

org.parboiled:main module.xml

Code:

<resource-root path="parboiled-scala_2.10-1.1.6.jar" />
<resource-root path="scala-library-2.11.1.jar" />

I am not sure if i got the best versions of parboiled-scala and scala-library, but it works now :) Yay! :D

Thanks Mattysek,
that is very helpful.

I will check the versions and send a patch soon (unless you want to contribute to the project and fix the issue yourself).
Usually we spot this kind of errors using integration tests, but we haven't got one for neo4j yet.

Cheers,
Davide

Thanks for reporting the issue and a solution, Mattysek!

As Davide said, we're still lacking an integration test for Neo4j. If you like, send a pull request with your fix (and if you like and integration test for the Neo4j backend running on WildFly, e.g. based on the ones we have for MongoDB and CouchDB), we'd be more than happy to integrate it.

Hi, thanks, no problem :)

I can certainly try and fix issues with missing dependencies in neo4j module. I also very briefly looked on integration tests but unless i am missing something neo4j test extending ModuleMemberRegistrationScenario would fail on not being executed inside a transaction when executed using arqullian in container, so what could i try to make it work? :D

Hi Mattysek,
I've seen your reply only today and I've actually start to wokr on the issue already.

This should be the branch with the fixed modules: https://github.com/DavideD/hibernate-ogm/compare/hibernate:master...DavideD:OGM-553-Neo4j-missing-dependecies?expand=1
I'm actually writing the integration test right now.
