It is a shot in the dark, but I have tried everything to reinstall Eclipse. I did the normal
apt-get install for Eclipse.
I used it for a year. And then I decided I wanted to select the "Upgrade Option" from the Eclipse Help menu. After 30 minutes of many downloads, I restarted Eclipse and none of the perspectives worked. Essentially, when I tried to upgrade through Eclipse, nothing worked afterwards.
I did the
apt-get autoremove and many ways to remove from Eclipse.
I tried to remove eclipse through apt and also removed some /lib files. But everytime I install I end up at the same place, Eclipse just won't work. I am sure there are residual files out there, I just don't know where.
When I download Eclipse from the site, it works fine. I am OK with working this way but I thought I would ask if there is a way to fix the eclipse configuration that comes with Ubuntu.
