Hello,

My copy of Helios is reporting an error message in the log file when I attempt to start it (Windows 7 platform). The splash screen appears briefly but then promptly disappears and there's no exclipse.exe process to be found running.

Here's the error message in the log file at workspaces/.metadata/.log:

You don't say whether you've every successfully started it before or
not. It sure helps to provide context. Assuming this is the case, the
usual culprit is failure to specify a valid JRE or JDK in eclipse.ini.
Note that if you're going to develop in Java, you'll want an actual JDK
and not merely a JRE there. Please see

http://wiki.eclipse.org/Eclipse.ini

Thanks for the reply.

Yes, I have successfully started the application previously. This behaviour started when the PC crashed as the application was shutting down yesterday.

Maybe workspace/.metadata/.plugins/org.eclipse.core.resources/.root/*.tree has been corrupted. Maybe.

So, rename workspace to workspace_old, start eclipse(new workspace will be created automatically), then import "Existing projects" from old workspace.

(If I were you, I'll delete *.tree, start eclipse(at this time, all projects will be vanished in the workspace), and then import "Existing projects" from current workspace without copying. But I'm not sure this is reliable.)

By now you could have reinstalled and tried again to see if it fixed the
problem. You can have as many copies of Eclipse as you like.

Look at the folders page in the eclipse instalation.

it could be in:

C:\Users\xxxx\.metadata\.plugins

I've removed some folders to test and I figured out the error was in the folder: org.eclipse.core.resources

I deleted it and problem solved!

It was due to an energy interruption who for sure must have corrupted a file.

I encountered very similar problem launching LiveCycle ES4 Workbench. When clicking on the icon to start Workbench, I got the banner for about 2 seconds and then it closed. I checked the log file and found the same message in the root cause of the stack dump. I removed org.eclipse.core.resources folder from my .plugins folder and restarted LiveCycle Workbench. Worked like a charm! Thanks. - Frank

The only thing I'd add to this is that in the above cases, C:\Users\xxxx\ actually refers to the workspace folder; it could be anywhere, not just under C:\Users.
