I’m continuing the Fuse trainings and I’m having a real hard time with the CodeReady package installed in Eclipse. In some projects, I am able to launch the Camel editor but with most, it doesn’t work. I get this exception described in the text file included as attachment.

This morning, I’ve compared the Eclipse files from one project where it works (Spring) with another one that doesn’t (Spring also).
I’ve compare the .project file, .classpath, and all I found in the .settings directory. I’ve synched both projects where applicable and still, the broken project spits me that error and the editor stays empty.

Any clue to fix this issue? It really is a show-stopper.
