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.

Answer 1

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...

Answer 2

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

Answer 3

rm -f ~/.eclipse/ is what worked for me!

Answer 4

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

$> eclipse -clearPersistedState

Answer 5

I just did a restart to the system and it started working fine.

Answer 6

Here's what helped me solve my problem:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=389738

Answer 7

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.

Answer 8

that fixed it for me:

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

Answer 9

With me, the loader froze on MyLyn. Finding another issue somewhere said to try deleting the stuff .metadata/.mylyn under the workspace directory gave me the ability to load my workspace again

Answer 10

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

Answer 11

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

Answer 12

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

Answer 13

I had to reinstall my mercurial plugin, that was the underlying issue for me.
