Not automatically as far as I can tell. Yes, the Java-GNOME jars have a
source zips but you have to manually add them. I asked about this when
3.0 came out but didn't hear anything and I briefly looked into to
yesterday, but came up with nothing again. I don't have time to
investigate it fully, so I think I'll just file a bug see what they
say.

Yeah, that a good idea and I've wanted this for a while. I was thinking
of checking a known location, for example if you add
package-version.jar, it would auto-attach package-version-src.zip. This
seems to be a convention that eclipse uses. But using a manifest file
tag would be more robust. Perhaps supporting both would be a good idea
using the manifest as the preferred source. 

The only concern I have heard about providing these zips on a large
scale is that the source code is already provided in the debuginfo
packages so making the source zips puts the source code in two places.
However, there are a couple of issues with using the debuginfo packages
like this:

1) AFAIK not all mirrors carry the debuginfo packages and they're not 
   enabled by default which means it's hard to rely on them
3) debuginfo generation of Eclipse and I think other java packages is 
   broken ATM

As far as doing the work, I personally don't have the time to do it, but
I'll make sure it gets on a general tasks list on the Eclipse Linux
packaging wiki.

HTH,
