Eclipse hangs
This worked for me today - saving it here so I can find it again
http://off-topic.biz/en/eclipse-hangs-at-startup-showing-only-the-splash-screen/
cd .metadata/.plugins
mv org.eclipse.core.resources org.eclipse.core.resources.bak
Start eclipse. (It should show an error message or an empty workspace because no project is found.)
Close all open editors tabs.
Exit eclipse.
rm -rf org.eclipse.core.resources
(Delete the newly created directory.)
mv org.eclipse.core.resources.bak/ org.eclipse.core.resources
(Restore the original directory.)
Start eclipse and start working. :-)
