Hi,

I'm trying to reuse emf models from existing plug-ins in a new emf project.
I can add the plug-ins in the target platform but don't want to import their source in the workspace as I am not going to edit it (I might not have the source at all).

Since the plug-ins are in the target platform, compilation against them is fine, but referencing them in the new .ecore model is not.

The tooling does not seem to find the types defined in the existing plug-ins.

I tried to set a reference element's EType with the following value:
ecore:EClass platform:/plugin/<Existing Plug-in>/<model Dir>#//<ModelElement>
but it did not do any good.

Could someone give mi a hint how this scenario would work?

Thank you!
Dimitar

Hi Dimitar

The Sample Ecore Editor often provides a good way to practice and some
XMI to analyze.

Open your new Ecore file, Load your old resource and select your class
as the relevant type.

This gives you something that will work.

The editor will deresolve the references so you will seesomething like
.../../../existing-plugin/model/Model.ecore#/something, which you can
change to platform:/plugin/existing-plugin/model/Model.ecore#/something
if you want.

In a plugin environment platform:/plugin accesses should just work. In a
standalone environment you need to initialise
EcorePlugin.platformResourcemap[ correctly. See
https://bugs.eclipse.org/bugs/show_bug.cgi?id=361063 for example code.
