I am developing an xtext plug-in project for an eclipse application for my Bachelor thesis.
I want to do the 'Generate Xtext Artifacts' at runtime with an ant script executing the Mwe2Launcher class and do the generation in an temp folder.
I wrote an Activator to create in the temp folder a project folder and copy the mwe2 file, my grammar file and the ant script.
Executing the Ant script leads to this error:

The ".java" file which are unmapped were also not generated. The whole "/src-gen/...../foobar/foo" folder is missing.
I guess this is the reason and what should be fixed.
I really don't know, where the problem is. I already had a discussion in an Eclipse forum there you can find the build.xml but for another project, also an Activator class to activate the plugin and do the copy stuff and execute the ant script, also you find the mwe2 file I use.
