Well, actually to be honest, the situation is moreso
# yum install eclipse-platform eclipse-stuff-i-need eclipse-stuff-i-kinda-dig eclipse-wtf-is-this-stuff
...which brings me to my problem: I'd been using a hand install of eclipse, maven, ant and a few other things when I upgraded from fc15 to fc17. On cleaning up, I noticed that there were newer yum installs for several of these things, and so set about obsolecing the old hand installs.
Everthing checked out until I got finally to eclipse, which seems to have a lot installed, but only a subset show up in the IDE. Specifically, the ide seems unaware of maven or subversion, aka eclipse-stuff-i-need, which I thought was installed.
I have not found anything which describes what else might be needed to control which features show up in the ide by default. I'm thinking that I shouldn't need to touch the internal eclipse installer for anything at this point, if ever. Am I supposed to add to a local config.ini?
I did find this article, which I have read through Eclipse#Troubleshooting_Eclipse_in_Fedora
on the Fedora Project wiki, and so have done the tests of the eclipse rpms, erased and reinstalled them cleanly (though en masse). Logs look clean.
Odd thing is that the bundle.info in ~/.eclipse is longer that that in /usr/lib64/eclipse.
I'm at a loss as to what to try next that doesn't involve hand-tweaking the installs. Suggestions?
