Now, after a bit of a gap, on to the business of installing Eclipse on Linux. In my case I'm using Crunchbang but I assume the same is true of any Debian based distribution of Linux.
I suppose it's worth pointing out that eclipse doesn't need to be installed as such, just extracted to wherever it's going to live.
So, I have downloaded eclipse-jee-ganymede-SR2-linux-gtk.tar
Next, before installing eclipse, I opened a terminal window and ran the following command to install Java first sudo apt-get install sun-java6-jdk
Next, extracted the eclipse-jee-ganymede-SR2-linux-gtk.tar archive to a folder of my choosing
Housed within this folder is an executable file called eclipse. Double click and Huzzah!
Easily the most straight-forward install ever (maybe not ever but you get the idea)
Now that that has lulled me into a false sense of security I know it's only going to get harder from here on in....
