Description of problem: Yesterday I did a routine yum update which updated my eclipse components (platform, swt, rcp, jdt) from 3.7.1-4 to 3.7.1-7. This caused major breakage - lots of error messages at startup, missing perspectives (Java), loss, I didn't capture all of the details at the time, but see steps to reproduce below. Version-Release number of selected component (if applicable): 3.7.1-7 How reproducible: Totally Steps to Reproduce: 1. yum erase eclipse* 2. yum install eclipse-jdt 3. run eclipse 4. New Project does not have a Java project as an option Actual results: No "Java Project" support Expected results: Naturally we would expect "Java Project" Additional info:
This situation occurs because we had to break a packaging loop by moving a plugin from eclipse-jdt to eclipse-platform. Unfortunately, without invasive, fragile workarounds, the only way to fix this is to stop Eclipse, mv ~/.eclipse{,.bak2011-12-21} and restart Eclipse. Some user preferences may be lost and plugins you manually installed (qt, it sounds like) will be gone but you should get the RPM-installed plugins back and you'll be able to re-install anything you previously installed from within Eclipse. We apologize for this issue and are working on a more robust solution to ensure it never happens again. *** This bug has been marked as a duplicate of bug 760454 ***
Yes, nuking my .eclipse tree did the trick. Thanks! -- Charlie
