Scala IDE: Scala Library error on a new project

Created my first project in Scala IDE and got this error on my project:

"Unable to find a scala library. Please add the scala container
or a scala library jar to the build path."

It seems that the project build path is missing the Scala system library. To fix:

– right-click project, click Properties

– click Java Build Path, then Libraries tab

– press Add Library button, select ‘Scala Library’ and then ok.
