I've been out of the Eclipse world for about two years but that was always something that confused me. With Eclipse it was also so hard to find the right version to download. You couldn't download Eclipse, you downloaded the Something pack or the Other Thing pack.

Then there were plugins you might want but they were only distributed as Eclipse installs so you either had to install that version or download it and steal the plugins you wanted out of the directories after you unzipped it.

Once you got it running it wasn't much of a problem, but it was one of those things that I hated dealing with the few times it was necessary.
