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

I had the same problem. I tried all sorts of things. And I came to know that

1. My .java files were not linked and
2. they were not placed in the 'src' folder.

Things I did:

Project properties >> Java Build Path >> Source

• Deleted the original 'src' folder which was empty using 'Remove' option
• Added the source that contained my source .java files using the 'Add Folder' option

This solved the error.
