How do I get the E4 Orion CSS Preference editor installed on Eclipse?
Today I again got angry that the launch of Eclipse Luna, the most recently used tab, was disabled by default. I searched for the problem and found a question to move Eclipse tabs and keep the previous open file (..) which both suggest reactivating it either by switching to the classic theme in preferences or to edit the Eclipse CSS.
But switching to the classic theme doesn't seem to work in my case, maybe because I'm using STS or a too recent version of Eclipse, I don't know. So I decided to try the second option. Following the link on the Eclipse Wiki and started to struggle:
The url they provide for the update site doesn't work in my Eclipse:
http://download.eclipse.org/e4/updates/0.16/ . I tried using the top version
http://download.eclipse.org/e4/updates/0.17/ which works sometimes and sometimes not, but the Eion Orion CSS preference editor doesn't seem to be available in 0.17.
So how do I get the correct url for the package?

The answer was in the Eclipse E4 wiki : go to E4 , find the link matching the repository you want. This is the 0.16 Stable build we want. In the bottom right corner of this page, you will find the online p2 repo link, which is the url I was looking for:
http://download.eclipse.org/e4/downloads/drops/S-0.16-201408072200/repository
I pasted above the relevant url, but don't click on it, you will get an error. It is actually meant to be copied to the eclipse panel "install new software ..":
Proceed with installation as usual and you can finally edit your CSS like on the next screen. Remember to restart Eclipse again so that it respects the CSS change.
Hope this helps someone else. This is all pretty simple, but since Eclipse is soooooo loooooooooonnnnnnng, before telling you that it cannot solve the repo, it took me a while to figure out how it goes.
