Eclipse JUNO doesn't start

Question

When I launch Eclipse, it does not start.
An error appears and tells me to see the log file.
"See the log file: /Users/max/work/projects/.metadata/.log"

OS: MacOS 10.7.4
Eclipse: 4.2 Juno
ADT: 20

My old version of Eclipse starts without issue.

I'm in a new folder, install a new Eclipse: /Application/eclipse - old /Application/eclipse4 - new — Max Bublikoff, Jul 03 '12 at 12:36
go to the help menu and click on "Check for updates", update it and than try... That worked for me...But since it is not even starting for you.. I think you need to re install it... — Amit, Jul 03 '12 at 12:39

This works for me, but I don't really understand why. What is this .snap file? – Ida Feb 26 '13 at 04:29

I think ist kind of a snapshot file which sometimes is corrupted – ligi Feb 26 '13 at 10:08
Worked for me, thanks. FWIW, the error happened immediately after I used git stash to revert lots of changes and additions in an Android project. – Umopepisdn Nov 02 '13 at 03:34

Deleting .metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi solved the problem in my case.

this worked for me (removing org.eclipse.core.resources resulted in eclipse still not opening), but what information have i lost by removing this file, and is there a way to recover it from the file? – inor Oct 10 '12 at 05:55
Thanks a lot..Works for me :) Even I dint have .snap file..Thanks a ton – aasha Mar 15 '13 at 06:11

.Snap file exists only while Eclipse is opened. If the file still there when eclipse is closed, you have to remove it. If you remove workbench file, you will lose the Eclipse layout. Anyway, removing workbench.xmi solves the problem. – Milton Mar 27 '13 at 12:00

I had to delete both of the following files as suggested in other answers to solve my issue,

.metadata/.plugins/org.eclipse.core.resources/.snap
.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi

worked for me as well, however I deleted folders mentioned in: http://stackoverflow.com/a/13620144/1581069 first (not sure if that was required as well) – Peter Butkovic Nov 13 '14 at 10:54
Deleting the folders aren't required. Just plug this flag into the command line, and you have your Eclipse set up. You still need to reorganize your Eclipse perspectives. – tom_mai78101 Oct 20 '20 at 00:50

Unfortunately, it did not work for me since I did not have .snap under

<home>/.metadata/.plugins/org.eclipse.core.resources

I ended up with the following sequence:

cd <home>/.metadata
mv .plugins .plugins.failing
<start eclipse>
<exit eclipse>  <--- builds fresh .plugins
cp -r .plugins.failing/org.eclipse.core.resources .plugins/org.eclipse.core.resources  <-- restores existing projects

I had a similar problem but on Win7 - 64. Deleting the .snap file allowed me into Eclipse and then I had to refresh my resource file via File-->Refresh.

The snap file is located: YOUR_PROJECT_DIR/.metadata/.plugins/org.eclipse.core.resources/.snap

I had the same problem twice on Windows: Eclipse didn't start because of the ADT plugin.

I removed temporary files and cleaned up Registry using CCleaner. Then it worked.

If you look in the eclipse.app content check if there is still eclipse.ini found that some updates destroy this file...

That was the reason on my system, copied it from a new version and it worked again...
