Maybe it's 'by design' but if you try to compare resources with no or
empty URI, the resourceURISimilarity method fails with an
ArrayIndexOutOfBoundException on line :

final String referenceName = reference[reference.length - 1];

Best regards,
Guillaume

Hi Guillaume,

Can't say this is "by design", it's more that we didn't protect the code
against empty URI resources since most of the code assumes your compared
resources are contained within a resource set, and they have legal URIs.

Do you have a legit use case where we should be able to compare
resources with no URI? If yes, then please raise a bug with the
information and (if possible) sample models for which the code should be
functional.

Hi Laurent,

I'm parsing text files (not XML) and generating models from those files.
The resulting EMF model is not to be persisted so the EObject is not
associated with a resource. Actually I saw I needed to add it to a
resource before using EMF Compare. What would you recommend ? Create a
dummy resource for any object I want to compare - with a valid URI ? Or
rise an enhancement request to allow comparison with EObject not linked to
a resource ?

Best regards,
Guillaume
