Neo4j cypher compiler for Scala 2.11 - dependency on parboiled-scala_2_10

[Andrzej Dębski]

Hello

I am using Neo4j database in my Scala application and I encountered a problem with updating to Scala 2.11.1. 

After changing Scala version in my sbt build files I got the message that:

[error] Modules were resolved with conflicting cross-version suffixes in {file:somePathTo}SomeProject:

At first I was thinking it is because on my dependency on Spray which also uses parboiled so I asked the question on their user list: https://groups.google.com/forum/#!topic/spray-user/XY7ceh7a9t0 where I got a suggestion to compute dependency tree for my project. 

I discovered that neo4j-cypher-compiler depends on parboiled-scala_2.10 which is causing the problem. Are there any plans to release version that supports Scala 2.11?

Hi Andrzej,

I raised an issue with neo but they closed it: https://github.com/neo4j/neo4j/issues/2881

Looking at the neo codebase it seems like it's a huge maven project so I have no idea when this problem might be resolved.
