Hello,
Here is my problem : I have a model, provided by a plug-in through an extension point. I'd like to be able to make changes to this model at runtime, so I tried to copy it. The problem is that this model may have many dependencies, and I'd like to copy these dependencies as well.
There are two kinds of dependencies : Absolute URIs, which I don't wish to copy, and Relative URIs, which I'm interested in.
The problem is that I can't list the folder's contents, as it cannot be converted to a java.io.File (It is a platform:/plugin/... URI, which isn't a file)
Is there a way to do this copy ? I considered loading the whole ResourceSet (To load all dependencies), then filter the resources I'm interested in, but it seems very expensive, compared to a simple folder copy. Moreover, I don't know how to load the whole ResourceSet.
Any pointer would be really appreciated 
Thank you,
Camille Letavernier

You could use FileLocator.toFileURI; be warned it will unpack jars to
create a copy.

EcoreUtil.resolveAll can help with that.

I wonder though how much performance is really a concern in the end...

EcoreUtil.resolveAll will help.
