I have some DSL plugins A, B and C. A uses B and C. When I create e resource with A I always get the following error if A uses a resource of C.

I although have another plugin D that uses B and C without errors.

I checked the MANIFEST.INF files for missing dependencies but I could not find any.
All used resources are already saved to disk nothing in the parsing state.

What could be the reason for that behaviour.

The uri you use looks strange to me. Where does it come from ?
Using dot inside a classpath is usually replaced by a slash.
And the name looks like a plugin name
But then you won't need it. So just classpath:/xxx.yyy

So can you give some more context

What context infos do you need ?

The DSL plugin that runs the DSL file has dependencies to 'npsm' plugin and the plugin containing the DSL file has the same dependencies to the 'npsm' plugin.
It seems to be a classpath issue but I don't know witch plugins classpath is improper.

Thank you

Since I have NO idea what you are doing inside your plugins I can only guess.

Can you give some hints on the structure of the plugins and the model projects

Where ever is the model file
Where is the file that cannot be found
How do the projects relate to each other?

Did you try to debug the place of the error?
What instance is the classloader of
If it is a bundle classloader which bundle is that?
....

P.s. Eclipse sometimes does wired things so maybe it helps to delete the runtime workspace and recreate it.
And: if you introspective the classpath / library etc of the model project in package explorer can you see the file there?

Thank you, this was the right answer. Recreating the runtime-workspace did the trick.
