Eclipse Juno Startup error log file

Question

I've been using Eclipse Juno perfectly fine until recently when I started it up I received the following error:

An error has occurred. See the log file C:\Users\Quinn\workspace.metadata.log

I've relatively new to programming so any help in layman's terms would be greatly appreciated. Thanks!

The .log file was incredibly long so I'm only adding the last part. If you need more info. please don't be afraid to ask. Thanks!

This isn't just a Juno error - I got the same error with Kepler. Gabriel's accepted answer below solved it. — 8bitjunkie, Feb 17 '14 at 12:41

I am having the same problem with Eclipse Juno, which I use for Android development.

As a workaround for Windows, I launch it from the console like this:

C:\path\to\eclipse\eclipse -clean

As hinted here, you can also try to delete the file YOUR_WORKSPACE/.metadata/.plugins/org.eclipse.core.resources/.snap

This also worked for me and (so far) seemed to fix the problem permanently, unlike the first option.

There is no .snap ! And clean not working. so what can i do now?! – Dr.jacky Mar 02 '14 at 16:21
Hi, Mr. Hyde. If you're using Eclipse Kepler, it appears that there is indeed no .snap file anymore. Since I cannot reproduce your problem (it all works well for me), could you tell me what error you are getting exactly? If you try @jayeffkay's answer below, does it fix your problem? – Gabriel Mar 02 '14 at 20:21
@HarmeetSingh good to know. Kind of sad to hear that this problem persists into Eclipse Luna though – Gabriel Sep 05 '14 at 17:01

I got my workspace starting again by deleting

org.eclipse.e4.workbench

from the .plugins folder. Then starting with the -clean flag.

This removed all my projects in the workspace. You could as well just delete the .metadata folder... – Daverix Jun 17 '13 at 18:53
Thank you so much! This worked for me, but not the previous tips I've seen here! I just lost one class, don't really understand why... But it's an easy one to "recode" – ccoutinho Jun 27 '14 at 09:07

In Mac you need to delete this file of your workspace

.metadata/.plugins/org.eclipse.core.resources/.snap

Cut the plugin folder out org.eclipse.core.resources [may be to the desktop] and start the eclipse. Now, you will see the eclipse open with out the projects. Now close the eclipse and Copy the plugin folder back again and start the eclipse. Now you should see all your projects with eclipse working open.

Go to your eclipse workspace and locate the .snap file in the given path

.metadata/.plugins/org.eclipse.core.resources/.snap

deleting the snap file should do the magic, what are .snap files well AFAIK

.snap files contains all the changes in workspace state of the IDE during the runtime and are used for eclipse crash recovery plan.

Just delete the org.eclipse.core.resources folder at Workspace.metadata.plugins. But you will have to import all projects to the eclipse again hence we delete the resource handling folder of eclipse. Hope this helps
