I am building an RCP application, where there will be updates in the features/plugins every quarter. So, if a user chooses to auto update the feature/plugin then new jars for updated plugins are getting downloaded, but the old plugins are still using my disk space which are no more in use.
I have tired deleting the installation history which has the information of old jar. While I try to delete it, it shows me the below given message
But this does not delete the .jar, I can still find it in my feature/plugin folder.
Also, this is a manual process. So, is there any way where the old plugins gets deleted automatically when there is new jars with updated version.
