[EMF Compare] Ignore order in EMFCompare [message #1046737]

I'm comparing ecore models and the following example returns an EMF Compare move. In the following example I move the name Attribute. The same happens when I change the order of the classes in the ecore model.

original code:

<eClassifiers xsi:type="ecore:EClass" name="Author">
    <eStructuralFeatures xsi:type="ecore:EAttribute" name="name" eType="ecore:EDataType http://www.eclipse.org/emf/2002/Ecore#//EString"/>
    <eStructuralFeatures xsi:type="ecore:EReference" name="test" eType="#//Book" eOpposite="#//Book/test"/>
  </eClassifiers>

moved "name" element

<eClassifiers xsi:type="ecore:EClass" name="Author">
    <eStructuralFeatures xsi:type="ecore:EReference" name="test" eType="#//Book" eOpposite="#//Book/test"/>
    <eStructuralFeatures xsi:type="ecore:EAttribute" name="name" eType="ecore:EDataType http://www.eclipse.org/emf/2002/Ecore#//EString"/>
  </eClassifiers>

They are not breaking the generated code. Is it possible in EMF Compare to set these changes to be ignored?

Aleksandar,

EMF Compare does not detect "changes that break the generated code". It compares the two given models and detects differences between them, without any assumption that these models are used to generated code (and without assuming that this will be the "default" generated code). Ordering differences will be detected on all "ordered" features, as well as on "containment" features.

That being said, these differences can be ignored. Please see the FAQ on that point.
