I’ve been waiting for 3.7 to release so I can switch to M6, but now I can’t get eclipse to run.

Eclipse runs fine without MyEclipse installed. I downloaded and ran the installer, which completed fine. Every time I try to run M6 now, it gives me an error, and tells me to check my .log file.

In that file is a NullPointerException:
java.lang.NullPointerException
at org.eclipse.ui.internal.registry.RegistryReader$1.compare(RegistryReader.java:103)

If I uninstall MyEclipse, the error goes away.

Jason,
Did you follow these steps?

* Shutdown Eclipse 3.6
* Delete the directory <Eclipse 3.6 install dir>/eclipse/.config.  Note the directory name begins with a dot so it won’t be visible in the Macintosh Finder.  On the Mac, you’ll have to use the Terminal application to manually go to the eclipse directory to delete it.
* Start up MyEclipse 3.7 RC2
* Verify that the MyEclipse Preference pages are available from the Windows menu>Preferences

Yep, tried that, no change.

The release note implies that Eclipse will start, it just won’t show MyEclipse. My installation won’t even complete the startup.

Jason, can you open the .log file again (<eclipse install dir>\workspace\.metadata\.log) and paste the last 2 entries starting with:
!SESSION—————–

hopefully more detail of the error may help. In the mean time I’ll forward your problem on to others that may be able to help.

The errors indicate a problem trying to restore the state of the workbench. I’d suggest uninstalling MyEclipse, opening Eclipse and closing all editors and perspectives, then shutting Eclipse down. Next, install MyEclipse and follow the instructions that Riyad pointed out at that point.

If you left Eclipse is a complex UI state when the config was deleted, it might be an issue. Another way to test would be to install a clean version of M6, open it, close it, install MyEclipse, then follow the special ‘.config’ instructions.

Could the problem be caused by my having a parallel 2.1.2/2.7RC2 installation in another directory?

jason

[Jason Bennett]

Success. This time, I made sure to install 3.7 in a different directory from 2.7. I didn’t think those would conflict (different version numbers), but apparently they did.

Glad to hear its working
