Basic Scala program gives error on JetBrains/Idea/intelliJ

Question

I'm running scala 2.8.0 SDK & Scala Plugin 1.5.2 (latest version) on IntelliJ 14.1.4 (also latest) with java-7-openjdk

object HelloWorld {
  def main(args: Array[String]) {
    println("Hello, world!")
  }
}

This is the error I'm receiving

Is there any settings i might have to change to get this to run? The program runs as a Scala Script on Idea IntelliJ

I must use scala 2.8.0 only not a later version, i'd be happy to change anything else

Try with scala 2.11.7 or 2.10.5 http://www.scala-lang.org/download/

Out of curiosity, have you tried to use a different JDK? Maybe JDK6 Hotspot or even JDK7 Hotspot?
I ask because I have seen errors similar to Error compiling sbt component 'compiler-interface-2.8.0.final-51.0' in the past, and they were usually related to incompatibilities with a library and a JDK version.

I cannot test right now, but I will give a look later and try to reproduce if it is still an issue.

For future travellers also setting up Scala for the first time:

I had similar issues and found changing the "Project Interpreter" to the correct JDK (OpenJDK 11 instead of my previous JDK 8) worked.

See e.g. https://stackoverflow.com/a/29286865/10447904

Many other SO answers that I stumbled across focused on setting the correct JDK using Settings -> Build -> Scala Compiler Server or on the configuration files, but neither of these worked for me.
