I am having trouble finalising the installation of Subclipse into my Eclipse installation.
First some background: I installed Eclipse in 64-bit Ubuntu (in a VM). I tried to install Subclipse but on the final screen, the button to finish was greyed out (apparently this is a known unresolved issue). I cancelled the installation.
The problem is that when I tried to add the plug-in again, it says that it's a duplicate location (http://subclipse.tigris.org/update_1.8.x). So I tried to search for the plug-in in the installed list (help -> about eclipse platform -> installation details), but I can't find Subclipse anywhere.
I have tried uninstalling Eclipse completely. Didn't solve the problem. I'd like to not have to completely reinstall Ubuntu in this VM. Is there any way I can completely clear any and all configurations so I can start from square one?
The following solution assumes you installed with the installer (as opposed to your package manager).
There is a hidden file in your home user directory (the path is /home/user). You can use the shortcut Ctrl+H to discover it.
And then you would find a folder named .eclipse, just remove this folder, as it includes all the setting you have set before.
Alternatively, you can open a terminal, and use the following command:
rm -r ~/.eclipse
Ubuntu, and all Unix systems are similar. They are all Inheritance systems, which will keep the user's setting in home.
