Hi,
I just whipped up some i386 test packages of Eclipse 3.3RC4 for F7. You can install these packages by adding this repo to /etc/yum.repo.d/ and then running 'yum --enablerepo=eclipse install eclipse-sdk':
[eclipse] name=Eclipse 3.3 for F7 baseurl=http://www.bagu.org/eclipse/3.3-F7/ enabled=0 gpgcheck=0
These packages aren't officially supported but I would still like to know if you find any problems.
Thanks, Ben
