Hi,
I guess you're using the "standalone example" as a base for launching
your comparison. You told you were loading the two models yourself, so I
guess you took care of registering all needed packages and resource
factories (such as what is given as example for UML on
http://wiki.eclipse.org/MDT/UML2/FAQ#What.27s_required_to_lo ad_a_UML_.28.uml.29_resource_from_a_standalone_application.3 F
).
I don't know what all the "integer" messages printed in the console are,
But the rest seems to tell EMF Compare indeed detected a number of
differences in your models ; you can iterate on the diff model's
eAllContent to check what all the differences are.
Seeing as what you're comparing are diagrams, I'd say you have IDs in
these models (xmi ids or functional ids). If the two diagrams have been
created in a graphical modeler at a distinct time (i.e they are not
"copy paste" of one another), then chances are the IDs of your elements
are different even if the elements themselves are identical. You'll have
to set the option MatchOptions.IGNORE_XMI_ID (or
MatchOptions.IGNORE_FUNCTIONAL_ID if yours are functional IDs) to true
for your comparison in order to avoid having EMF Compare detect
differences based on IDs alone. (This is done via the Map MatchService
takes as a parameter of all "doXxxMatch" operations.)
If this is not your issue, you can try comparing your models from the
Eclipse UI to see if EMF Compare behaves as expected when called from
the "standard" code. You only need to select your two impala_diagram
files in the workspace, right-click them and select "compare with =>
each other" to try this.
If none of this helps, I'll need more info as to what you get as
differences in order to try and understand what EMF Compare falsely
detect as different.
