Hi,

I'm trying to use EMF Compare programmaticly:

MatchModel match = MatchService.doMatch(referenceModel,
createdModel, Collections.<String, Object> emptyMap());
// Computing differences
DiffModel diff = DiffService.doDiff(match, false);

Both models are UML-models and they do exist (are not null).

Unfortunatly, the first line already throws a NullPointerException:

java.lang.NullPointerException

Hi Usul,

Judging by the fact you're calling the comparison from unit tests and
the failure appears right off the bat, my best guess is that you're
calling MatchService.doMatch() on models that are not contained within
Resources. You can either
1) call MatchService.doContentMatch() instead (that would see all
inter-model differences as "Add" or "Remove" operations)
or
2) create Resources to contain your models and possibly create a
ResourceSet to contain these Resources and then call
MatchService.doMatch() on it.
