Uninstall plugins during update [message #1555404]

I have a product in which some of plugins will become obsolete after and update. How should I proceed with uninstalling these plugins? UninstallOperation will not work because these plugins are not part of separate IU that can be uninstalled. I looked at p2.inf instructions, particularly uninstallBundle. Can I use that and if so how?

Thanks,
Alex

There is nothing to do to get plug-ins removed. As soon as a plug-in is no longer used by any other plug-ins, features or products, it is automatically removed.
Note that after an update, the jar files of the removed plugins will likely stay on disk but they will not be used. The file controling which plug-ins are used is in <install>/configuration/org.eclipse.equinox.simpleconfigurator/bundles.info.

Thanks Pascal.

I'll need to explain further I think. In our product current version of editor we have defines a namespace for EMF model. New editor that we've been working on uses the same namespace, so when two are loaded together we get error messages such as:

!ENTRY org.eclipse.emf.ecore 2 0 2015-01-09 15:29:15.178
!MESSAGE Both 'com.iwaysoftware.eclipse.channel' and 'com.iwaysoftware.channel.repository' register a package for 'http://consolesm.ibi.com/xml/repository'

!ENTRY org.eclipse.emf.ecore 2 0 2015-01-09 15:29:15.186
!MESSAGE Both 'com.iwaysoftware.eclipse.channel' and 'com.iwaysoftware.channel' register an extension parser for 'channel'

In addition we get two sets of wizards defined by newWizards extension points by new and old editor. I know I can remove old one with Activities, but I much rather if possible remove old plugins altogether based on particular criteria, like version. Is this possible?

If the new bundles for the editor, wizards, etc. have a different id, then make sure that they are not being referred to from any other plugin, feature or product.
Note that here I'm talking about the case where the product is completely built.
In the IDE, you just need to close the projects.
(though I feel like I'm missing details to help)

Thanks Pascal. The feature will change yes, but I thought about removing previous plugins altogether although from what I've read not sure if it's at all possible. I wanted to do this to conserve space that these plugins take up.
