I had been using eclipse in Ubuntu 9.10 without any problems. Recently I did an upgrade to 10.04, and it seems that my ~/.eclipse folder was overwritten. Now i tried installing my earlier plugins again, but when i restart eclipse, they don't appear. I can see these plugins in the "installed software" section. I can also see them in ~/.eclipse/plugins and ~/.eclipse/features

I did the following :
Copy the plugins installed from ~/.eclipse/plugins to /usr/lib/eclipse/plugins. Done the same for features too.

Now, when i run eclipse as sudo, i can see the plugins. How do i make sure that the plugins are seen when i dont run as sudo?
