access other plugins (without dependeny) [message #466573]

Hello,
in my eclipse RCP how can i access the API/packages of another plugin
that is not a dependency of myPlugin?

I am asking this because... I am writing a scripting engine plugin. The
script writer should have the possibility to access packages/instances
of other plugins. The scripting engine plugin development does not have
a list of all possible "other" plugins that might be from a third party.

Any idea?

You might like to try looking at the test suite, which does similar things.

You could also use OSGi tricks like Dynamic-ImportPackage: * which would then automatically bind you to an exported package on the system that you access via getClass. But this is only going to work when you just rely on the exported packages, and may be brittle in the face of updates or problems where multiple packages are exported by the same class.

Thank you very much for the hints,

As I am quite new to eclipse RCP,
could you specify your suggestions a little bit:
What test suite do you mean?

And the Dynamic-ImportPackage suggestion sounds cool, too. How can I do
this? Where do I find the getClass() function?

If you don't know about those, you probably aren't going to succeed in writing a scripting function that integrates with Eclipse.

Check out Neil's tutorial on this site about the 'osgi getting started' series if you want to learn a bit more about the bundles. You can also look at the test scripts and documentation at eclipse.org/articles; there's one on automated testing of Eclipse plugins there. It's located in the org.eclipse.test package IIRC.
