EcoreGenerator generates ImplCustom classes for foreign packages

[cdietrich]

with

  <eClassifiers xsi:type="ecore:EClass" name="RefExpression" eSuperTypes="../../org.eclipse.xtext.xbase/model/Xbase.ecore#//XExpression">
    <eStructuralFeatures xsi:type="ecore:EReference" name="ref" eType="#//ReqValue"/>
  </eClassifiers>

and

    component = org.eclipse.emf.mwe2.ecore.EcoreGenerator {
        genModel = "platform:/resource/yyyy/model/Zzzz.genmodel"
        srcPath = "platform:/resource/yyy/src"
        generateCustomClasses = true
    }

you will end up with a src/org/eclipse/xtext/xbase/impl/XExpressionImplCustom.java

@szarnekow any idea?

The code looks completely bonkers for the case that generateCustomClasses was set to true.
It is possible to register multiple src-folders to do the lookup. But if the first one does not contain the custom class, it is generated immediately.
Also the lookup from the classpath is only done after the class was already generated.

I think we need to move the generate stuff out of the loop for the processing.

Also: It might be reasonable to disallow multiple source folders if generateCustom is set to true.
