Tried to follow this tutorial (https://wiki.eclipse.org/Graphical_Modeling_Framework/Tutorial/Part_4) and to create an RCP Diagram Editor. Everything works fine, until the last step "Generate diagram editor" fails with this error message:
'Executable Templates' has encountered a problem.
Problems while generating code
...Details shows a bunch of:

I am new to eclipse and GMF and have no clue what i might have overlooked and wrongly configured. (I am using current Mars-Eclipse with the GMF-Stuff installed via "Help" > "Install new software") What could be the problem?
In the genmodel set the compliance to 6.0.
