Eclipse Java Missing required source folder: 'src'

Question

Description Resource Path Location Type
Project \'Interpreter1\'

Answer 1

Go to the Build Path dialog (right-click project > Build Path > Configure Build Path) and make sure you have the correct source folder listed, and make sure it exists.

The source folder is the one that holds your sources, usuglaly in the form: project/src/com/yourpackage/...
