Editor does not contain a main type

Question

Just going through the sample Scala code on Scala website, but encountered an annoying error when trying to run it.

Here\'s the code: http://www.scala-lang.org/node/

Answer 1

For me, in Eclipse 3.6, this problem occurs when my main method is not public. I caused the problem by having a main method like this:

static void main(String[] args) 

The dubugger was unable to detect this by itself. I am pretty suprised Eclipse overlooked this.
