I have just installed idea + scala plugin and had the same error on running my 1st "hello, world".

I solved it with Run -> Edit Configurations... -> select the script run configuration -> untick "Make" under "Before launch"

According to Getting Started with IntelliJ IDEA Scala Plugin:

You can also turn your Scala object into a script. Just remove all declarations from the file, leave the executable statement only - println("Hello, World!"), and run the script as described above.

However I confirm that it results with the same error as you quoted. I think this is a bug (or inaccurate documentaion), file a bug, Jetbrains guys are developing this plugin very actively.
