Description Nadav Har'El 2009-07-07 08:11:53 EDT
After upgrading from Fedora 10 to 11, Eclipse suddenly "forgot" all about Java development. It doesn't edit Java files (and rather opens Emacs!), it doesn't compile Java, and the "Java perspective" is missing from the "Open Perspective menu".

Needless to see, I still have the eclipse-jdt package, like I always had.

Trying to look if other people faced this problem before, I found these posts:

Things started working again only after I removed my ~/.eclipse directory. I don't know what was specifically wrong in this directory - it's a shame I had to remove it all (because it also removed some of my settings), but I can send someone a copy of this directory before I deleted it, if you're interested.

I am experiencing the same issue, though I've had Fedora 11 since the start.

Eclipse Java worked fine until I updated on July 3:

Jul 03 14:41:16 Updated: 1:eclipse-swt-3.4.2-11.fc11.x86_64
Jul 03 14:41:17 Updated: 1:eclipse-rcp-3.4.2-11.fc11.x86_64
Jul 03 14:41:27 Updated: 1:eclipse-platform-3.4.2-11.fc11.x86_64
Jul 03 14:42:27 Updated: 1:eclipse-jdt-3.4.2-11.fc11.x86_64
Jul 03 14:42:33 Updated: 1:eclipse-pde-3.4.2-11.fc11.x86_64

Previously, I had been using the -9 builds of these packages successfully.  It seems something in the -11 build broken Java editing...no Java perspective, no Java options, etc.
Comment 2 Eric Floehr 2009-07-07 09:31:10 EDT
Downgrading to the -9 builds restores Java and svn functionality, so it's definitely something in the -11 build:

yum downgrade eclipse-swt eclipse-rcp eclipse-platform eclipse-jdt eclipse-pde
Comment 3 Nadav Har'El 2009-07-07 10:03:37 EDT
This is probably the same bug as the one reported in bug 509616
Comment 4 Andrew Overholt 2009-07-07 10:35:34 EDT
Yeah, this bug is very unfortunate but we are focusing on getting the 3.5 series ready which is no longer affected by this bug.  Basically, we try to avoid updates :(  Sorry we had one in this case and that you were affected by it.
Comment 5 Eric Floehr 2009-07-07 10:51:28 EDT
Thankfully running "eclipse -clean" solves the problem, as noted in bug 509616.  Thanks.
