Most annoying -- I'm getting Problems opening perspective 'org.eclipse.cdt.ui.CPerspective' -- with several versions of Eclipse, using several different workspaces, is that the same thing?
Running Ubuntu 12.04, and all was working fine until I updated the system this morning. Might be related.

I am able to use the Java and Python perspectives just fine but I am getting the same error (Problems opening perspective 'org.eclipse.cdt.ui.CPerspective') along with the error:

The selected wizard could not be started.
Plug-in org.eclipse.cdt.ui was unable to load class org.eclipse.cdt.ui.wizards.CCProjectWizard.
An error occurred while automatically activating bundle org.eclipse.cdt.ui (514).

These errors happen on both the Indigo and Helios versions of Eclipse even after clean installs with both versions. Seems to be a common problem. Anyone out there with a fix?

Did you install Eclipse using the package manager on Ubuntu or did you download the zip file from the eclipse.org site?

If you installed using the package manager, uninstall and download directly from eclipse.org.

Both of these errors have happened on installs directly from eclipse.org and from the package manager. It happens whenever I try to use c or c++ at this point, no matter how I install or what other plugins I have.

Same problem here. While I was working CDT crashed (I used ubuntu 12.04 based eclipse+cdt). Workspace changed, same problem. Removed ~/.eclipse/$thecorrectone, same problem. Uninstalled eclipsed, downloaded Juno classic, installed CDT 8.2 from upate site, used a new workspace... still the same problem.

In the traceback I found a hint that lead me to (not allowed to post links?)

geloest-could-not-initialize-class-com-ibm-icu-impl-java-timezone

which showed me that appending this line to eclipse.ini

-Dcom.ibm.icu.util.TimeZone.DefaultTimeZoneType=ICU

circumvented (I would not say solved Twisted Evil ) my problem. WTF changed that this problem ocurred?

There was a recent upgrade of open-jdk in Ubuntu. This link references a problem relating to a missing file in time zone mappings.

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=600288

A re-install of tzdata-java may fix your problem.

Thanks for posting, was having the same problems today. For anyone who wants some command line help :

First shut down Eclipse if open. Open a command prompt.


sudo apt-get purge tzdata-java



Then after everything is removed, run this

sudo apt-get install tzdata-java


Now reopen eclipse and you should be good to go!
