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

run "eclipse -clean -refresh" from command line. This fixed the issue for me when all other solutions failed.

Answer 2

Just make sure that the folder you work in is added to the built path:

right-click your folder --> build Path --> Use as source Folder

and it should now find main therein.

Answer 3

What you should do is, create a Java Project, but make sure you put this file in the package file of that project, otherwise you'll encounter same error.

Answer 4

I have this problem too after I changed the source folder. The solution that worked for is just editing the file and save it.

Answer 5

You can try to run the main function from the outline side bar of eclipse.

Answer 6

File >> Import >> Existing Projects into Workspace >> Select Archive Filed >> Browse and locate file >> Finish. If its already imported some other way delete it and try it that way. I was having the same problem until i tried that.
