When I run it without modifications it passes successfully. Have you also tried that?

I'm confused. What's wrong and what's right in your opinion?

It strikes me that this is related to your modifications, which I can't judge. Please note that the plugin.xml of your
(example) model is not regenerated once it exists. Make sure the nsURI and Model Package classname match properly.

Hi Eike,
thanks for your advice. Gefahr erkannt, Gefahr gebannt :)
it was the extension point that was outdated (modelPackage instead of
ModelPackage) in the plugin.xml of the model proeject:
<extension point="org.eclipse.emf.ecore.generated_package">
<package
uri="http://orgstructure/1.0"
class="com.emfdbexample.orgstructure.model.modelPackage"
genModel="model/orgstructure.genmodel"/>
</extension>
Regards
Kris
