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!

Answer 1

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.

Answer 2

I got my workspace starting again by deleting

org.eclipse.e4.workbench

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

Answer 3

In Mac you need to delete this file of your workspace

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

Answer 4

Delete: /[PATH TO WORKSPACE]/.metadata/.plugins/org.eclipse.core.resources It will get eclipse back to work

Answer 5

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.
