Huh, our EGit update sites no longer have a site.xml file, and are
instead returning an HTML error page with "404 Not Found" message
on them.

Chris, any idea what's going on?

I checked our download site using Eclipse Provisioning Admin UI and this finds all the

p2 metadata it expects so it doesn't look broken from p2 perspective (don't know what this tool

covers in detail). 

I downloaded Zend Studio and will try to reproduce Steven's problem.

I installed Zend Studio 7.2 and then installed egit 0.7.1 from http://download.eclipse.org/egit/updates

via "Help > Install new software" and everything worked as expected (see attached screenshot).

Note that this will only work if using P2. The old update manager uses site.xml, whereas P2 looks for artifacts.jar. 

It is possible to configure, in 3.4, whether P2 is used or not as follows. I believe you will be able to recreate the problem by enabling the "classic update" option, which will then make it look for site.xml (and fail). 

Is there any reason we don't publish a site.xml file as well to enable this case? There are those who thought (particularly earlier releases) that P2 wasn't stable enough for general use and will have disabled it.  

Interaction with legacy Update Manager

In Eclipse platform version 3.4, the old Update Manager still exists under the covers for backwards compatibility. You can even re-enable the old Update user interface by enabling the "Classic Update" capability on the General > Capabilities preference page.
