Hi All,

I have been working on a project with GMF and GMF Tooling, but a while ago it broke due to some update and i couldn't generate code anymore.

The version I found that still works is GMF Tooling 3.2.1.
Now i can generate code, however i am getting this error when running the application:

Bundle was not resolved because of a uses constraint violation.

I suppose it has to do with the org.apache.batik version required by GMF Tooling beeing outdated, however I do not know how to fix this issue.
Currently there are two org.apache.batik versions installed, 1.6.0 and 1.16.0.

Any help on how to tackle this issue is appreciated.

Thank You

The error seems to indicate that the 'org.eclipse.gmf.runtime.diagram.ui.render' bundle is exposed to the 'org.w3c.dom.events' package from two different sources, causing a uses constraint violation.

One way to potentially resolve this issue is to try to isolate your environment so that there's only one version of each package. You can try uninstalling one of the versions of 'org.apache.batik' to see if that resolves the conflict.

Also, check your target platform and make sure it contains the correct and consistent set of plugins. This is often a reason for such issues.

If the issue persists, you may need to manually resolve the dependencies, which can be time-consuming and complex, but usually works.
