(eclipse) cloned repository project missing gen folder

Question

I cloned this: git repository into eclipse workspace. I am interested in Xtext-XML sample only. Because i want to create a domain specfic language generating xml code. Thats seems the only example at this topic.

My problem is that on the build path the '/src-gen' folders are missing. All the projects have a red exclamation mark in the package explorer. How can i generate those missing files.

Answer 1

Check out the README.TXT file. There it says:

Start a new Eclipse Application and create an empty Java project. Add new source folder called "src-gen/" and put the following statemachine into a file in the "src/" folder.
