I like to develop java apps so I need a good compiler like Eclipse. But I did a mistake. I installed some updates and after that my compiler didn't work properly: I couldn't create a java project or an Android project. So what to do?
I thought that uninstalling and reinstalling the application would work, like in Microsoft OS. But not... I had to remove the old configurations...
So I tried some ideas and now I'll show you how to reinstall Eclipse without using old configurations.
-
uninstall Eclipse using Software Manager or from terminal: sudo apt-get remove eclipse;
-
type ALT+F2 and then open nautilus as root( gksu nautilus);
-
go to HOME, press CTRL+H to view hidden directories and delete .eclipse directory;
-
install Eclipse using Software Manager or from terminal: sudo apt-get install eclipse.
And now it should work...
