compare 2 models in elipse rcp [message #136755]

Originally posted by: foster963.yahoo.de

Hello everybody!
I want to write a Eclipse RCP Application which can compare 2 models and
show the differences in a model comparision editor. The differences
between the models calculate the plugin emf-compare and generate a
result.emfdiff . This already works fine, but the comparisioneditor
looks other than in eclipse and if I try to merge the models I get a
exception.

--> this line opens the editor from plugin org.eclipse.compare.CompareUI

ModelUtils.save(snapshot, "result.emfdiff");
ModelCompareEditorInput input = new ModelCompareEditorInput(snapshot);
CompareUI.openCompareEditor(input);

--> the exceptions if I try to merge the models

Can someone help me or is there a alternative to
org.eclipse.compare.compareUI.opencompareEdior()?

Thank you very much!

ok, i solved the problem.

you must add the following plugins to the runconfiguration:
for symbols:
org.eclipse.uml2.uml.edit und
org.eclipse.uml2.common.edit

and for the exceptions
org.eclipse.uml2.uml.resources

Hi Martin,

Yup, EMF Compare doesn't have dependencies on UML2 or any other
metamodel (save for ecore). Comparing models can only be done in an
environment where those models can be read in the first place. For UML
models, these means having access to org.eclipse.uml2.* mandatory plugins.
