FAQ How do I remove a plug-in?
You should not remove plug-ins from Eclipse. Plug-ins should be installed as features using the Update Manager. The same Update Manager can be used to disable plug-ins by disabling the feature they belong to. Run Help > Software Updates > Manage Configuration..., select the feature of interest, and disable it with the task shown in the right window.
When a feature is disabled, all its plug-ins will be disabled also. They are still available on disk, and they can be enabled at any time in the future. To physically remove the feature and its plug-ins, you will have to manually remove the feature from the eclipse/features directory and its plug-ins from the eclipse/plugins directory. We advise extreme caution here. Remove the wrong ones, and you may have quite some trouble restoring your Eclipse to a stable state. Unless you care a lot about hard disk use, we recommend leaving the plug-ins where they are.
