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.

Solution 1

that fixed it for me:

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

credit: http://www.metod.si/job-found-still-running-after-platform-shutdown-eclipse/

Solution 2

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

Solution 3

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

Solution 4

Running eclipse from the command line with the -clearPersistedState switch fixed it for me:

$> eclipse -clearPersistedState

Solution 5

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

Huge:~ max$ ls -la work/projects/.metadata/.plugins/org.eclipse.core.resources/‌​.snap ls: work/projects/.metadata/.plugins/org.eclipse.core.resources/‌​.snap: No such file or directory

[ligi]

very strange - can you do a ls -la work/projects/.metadata ?

[Vitali]

fixed it for me too. still crops up every once in a while.

[inor]

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?

[Krishnabhadra]

I too didn't had .snap folder in my workspace.. This solved the issue for me for sometimes.. It again props up often..

[IgorGanapolsky]

I don't even have a .snap file

[prashant]

Thanks. This worked for me too for eclipse Juno available with Android SDK download.

[Adam]

doesn't work - Eclipse Juno corrupts 90% of all projects this way. It's completely unusable :(.

[Ida]

This works for me, but I don't really understand why. What is this .snap file?

[ligi]

I think ist kind of a snapshot file which sometimes is corrupted

[PlunkettBoy]

This worked for me on a Win7 box. Java 1.6u43. How much does IntelliJ cost again? ;-)

[aasha]

Thanks a lot..Works for me :) Even I dint have .snap file..Thanks a ton

[Milton]

.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.

[Umopepisdn]

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.

[Qantas 94 Heavy]

Please describe what this does and how it solves the problem. Without doing so, this would only be suitable as a comment, not an answer.

[Eric L.]

Genius! Fixed my Kepler SR1 (4.3?) after my sleeping computer lost power over the Thanksgiving weekend.

[Peter Butkovic]

worked for me as well, however I deleted folders mentioned in: stackoverflow.com/a/13620144/1581069 first (not sure if that was required as well)

[jonrsharpe]

Alright I'm getting bored of this - please remove the salutations from your questions and answers, they are just noise on SO.

[Juan de Parras]

This work for me in win7 and Kepler Service Release 2

[tom_mai78101]

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.

[andrefilipeos]

worked for me as well!!
