Plugin Required-Bundle [message #326684]

Hello,

Is there a way that 2 plugins A and B requiring different conflicting
versions of a common plugin can work in the same RCP plugin environment?

Plugin A has a requirement:
Require-Bundle: com.common.plugin;bundle-version="[1.0.0,2.0.0)

Plugin B has a requirement:
Require-Bundle: com.common.plugin;bundle-version="[2.0.0,3.0.0)

When plugin B is installed plugin A quits working. Is there a way
plugin A can use one version of the common plugin and B can use
another version?

Thanks,
Doug

Doug,

I think this can only work if the common plugin isn't a singleton (which
means it can't use or introduce extension points).

Bundles can do that ... plugins with plugin.xml cannot (since they have
the singleton:=true directive).

if your com.common.plugin doesn't have a plugin.xml it might be do-able.
