This seems like a trivial task, but I can't find an option to cleanly de-install the ADT from my Eclipse installation. Of course, I could just delete the folder of the SDK, but this just throws errors when starting up Eclipse the next time. The reason I'm asking is because my old ADT keeps throwing a wierd error (Failed to fetch URL https://dl-ssl.google.com/android/repository/addons_list.xml, reason: File not found) and I need a complete, fresh re-install.
Important: under Help -> about eclipse sdk -> installation details the uninstall button for all android plugins is greyed out
