I'm at a point where it behooves me to install an Eclipse development environment for Ubuntu. Not that I haven't done it before, but the last time I did, there were a couple of head-scratchers that I don't even quite remember anymore.
So anyway, I did a search on Google and ended up with a wonderful set of step-by-step instructions written by Hod at the Ubuntu Forums.
What's so great about it is that it documents the bugs that you may run into, and tells you how to get around them.
