2.11 neo4j

[omidb]

Hi,

what is exactly the problem of Neo4j and gremlin and Scala 2.11.4?

thanks,

[mpollmeier]

Neo4J has a (I think transitive) dependency on Scala 2.10, and one can't
mix Scala versions. As soon as they upgrade to 2.11 or provide a cross
compiled version (like Gremlin-Scala does) we can use 2.11.

This seems to be a quite old problem:
neo4j/neo4j#2881

[chrisbeach]

Currently in a nasty situation where another library in my project needs Scala 2.11 and Neo4J (embedded) is the only library I depend on that's holding me on Scala 2.10. Eagerly awaiting a Neo4J build against Scala 2.11.

neo4j/neo4j#4551 Is Gremlin-Scala now compatible?

[mpollmeier]

That looks promising indeed. The only thing to wait for is the TP3 neo4j driver - it already works with a custom local build of mine, but isn't officially released yet.

@mpollmeier can you send PR there?

[mpollmeier]

there's no code change necessary, it will be included in the next version of tinkerpop3 automatically. I built a snapshot locally which worked - you could do the same. once they release the next version I'll provide an example in gremlin-scala-examples.

[mpollmeier]

there's discussions on the tinkerpop dev list about an RC1 release on monday, so it shouldn't take much longer.

[mpollmeier]

rc1 has been tagged and will probably get released this week

@mpollmeier So how is it going with 2.11?

[mpollmeier]

tp3 3.0.0-incubating was released yesterday. I just released gremlin-scala 3.0.0 and updated the neo4j project - it now works with scala 2.11!

[omidb]

@mpollmeier nice! BTW, why you keep Gremlin-Scala as the name, I think you can also change the name to Tinkerpop-Scala!

It seems that Neo4j did not publish their 2.11 jars properly. If I do dependency-graph in this project (with https://github.com/jrudolph/sbt-dependency-graph), I can see that it depends on org.neo4j:neo4j-cypher:2.2.2, which depends on Scala 2.10 :( There is cypher-compiler-2.2_2.11, but no cypher_2.11.
