Intellij not compiling scala project

Question

So I have made a Maven Scala Project in IntelliJ.

I used the scala-simple-archetype.

And now I get this:

Error:scala: Error: org.jetbrains.jps.incremental.scala.remote.ServerException

Could anyone tell me what I've done wrong?

I'm relatively new to scala and maven so please bear with me.

Ok I just figured it out. Thanks to this post: Sbt doesn't compile...

You have to change the Version of scala in your pom.xml file from ${scala.version} to 2.11.4 (or whatever the newest version is)
