Hi,
Today I tested the following configuration :
Eclipse 2.1.3
- org.eclipse.gef_2.0.0
- org.eclipse.draw2d_2.0.0
and
- org.eclipse.gef_2.1.2
- org.eclipse.draw2d_2.1.2
I modified the plugin.xml where the import are specified by upgrading
the match attribute from equivalent to perfect.
The expecting result was two GEF and two Draw2d plugins recognized by
the platform.
However, only one plugin was recognized.
is this known ? is there a workaround ?
As this question is platform based rather than GEF based, please comment
I will post on the platform newsgroup.
Regards.

This is a limit in the runtime model. Only one version of a specific plug-in
can be active at the same time.

Put different versions into different plugins and give them different plugin
ids or just create binary jars and put them into your plugin. The Eclipse
classloader will do the rest.

Do you know if this issue is opened as a bugzilla/feature request at
eclipse.org ?
Is there somewhere a discussion on that subject ?
I cannot google the eclipse newsgroup in a clever way on that subject.

It's exactly what we are going to do.
This is the only solution for commercial provider. How to imagine a
user/customer who play with different commercial plugin if they use the
same plugin but at a different level version. A real mess occurs and a
large Headache for support.
This is particularly true on platform like WSAD and Netweaver.

Actually, the limitation is for plug-ins which define extension points. For
example, GEF has some UI keybindings defined in it.
One way to get around it is to create two separate plugins, one containing
just a JAR, and another containing just the extension pionts, but this would
require that the second plug-in be backwards compatible with the old JAR,
and its ugly too.

Hi,
Thank you for your thoughts.
However we have tested the cohabitation under Eclipse 3 and both plugins
are recognized. It seems that the eclipse team have improved their
runtime model. I am pretty glad to see that. It means that the version
and match attribute will be useful.
Is the problem your report about keybindings apply on eclipse 3.

I'm pretty sure there are no improvements in this area. 3.0 may *recognize*
plug-ins and display them as installed correctly (Maybe even 2.1 does this
too). But, once one of them is activated, the other cannot be activated
too. I'm not 100% sure, but I'd bet money on it.
