Hi, I am trying to play this library and run the file TheMatrixTraversalHack.scala, but always got below errors: /Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk/Contents/Home/bin/java Exception in

I guess something is wrong with libraries, below is my build.sbt:

import sbt.Keys._

name := "test2"

version := "1.0" scalaVersion := "2.11.8" resolvers += "Neo4J Maven Repo" at "http://m2.neo4j.org/content/repositories/releases"

libraryDependencies ++={ val scalaReflectVersion = "2.11.8"

val neo4jVersion = "1.9.4" val neo4jShellVersion = "1.9.4" val neo4jLuceneIndexVersion = "1.9.4" val neo4jCypherVersion = "1.9.4" val neo4jScalaVersion = "0.3.0"

Seq( "org.scala-lang" % "scala-reflect" % scalaVersion.value, "org.scala-lang" % "scala-compiler" % scalaVersion.value ,

// Neo4j graph database
"org.neo4j" % "neo4j-kernel" % neo4jVersion,
"org.neo4j" % "neo4j-lucene-index" % neo4jLuceneIndexVersion,
"org.neo4j" % "neo4j-shell" % neo4jShellVersion ,

//Neo4J Scala Wrapper Library
"eu.fakod" % "neo4j-scala_2.10" % neo4jScalaVersion,

// Cypher
"org.neo4j" % "neo4j-cypher" % neo4jCypherVersion,

} }

Any idea to solve this issue?

BTW, I was trying to use higher version of neo4j like 2.3.2, but always got warnings of version incompatibility, asking me to pick up one from two versions Thanks

it's the scala version . I fixed this problem using scala 2.11.x
