Hi Janboe,
If I understand correctly, you can "play around" with the version numbers and dependencies. For example, if you have modified org.eclipse.cdt.core, you can change the version number a little bit (probably best to stick to service segment, the third number)
and then add a dependency that is strictly on that version.
E.g. in MANIFEST.MF for cdt.core, change:
Bundle-Version: 6.9.0.qualifier
to
Bundle-Version: 6.9.987.qualifier
and in the dependent project do this:
Require-Bundle: org.eclipse.cdt.core;bundle-version="[6.9.987,6.9.987)"
Of course playing around with version numbers can have some unwanted side effects if you are mixing official CDT releases with your releases. Therefore you should try to make sure that you have some control on the update (p2) sites so that only one version
of CDT is available to p2 in the first instance.
HTH,
Jonah
