Multiple versions of an extension [message #335635]

Hi,

Requirement is as follows:

Plugin A defines an extension point. Plugin B provides the corresponding
extension. There are however, multiple versions of Plugin B. The
requirement is that all these versions should be available through the
extension point mechanism.

I have only been able to obtain the latest version of the plugin through
the extension point APIs ( IExtensionPoint.getExtensions(); )

Any pointers or suggestions are greatly appreciated.

TIA,
Best Regards,
- abhi

Abhi,

Plugins that contribute extensions must be singletons and while many
versions of such a plugin may exist, only the one that satisfies the
version range dependencies of the other installed plugins will be
activated while the rest will be as if they aren't there at all.
