Eclipse hangs at startup showing only the splash screen

맥에서 이클립스 시작 중 멈춰 갈길 안갈 때 처치법.

1. cd .metadata/.plugins
2. mv org.eclipse.core.resources org.eclipse.core.resources.bak
3. Start eclipse. (It should show an error message or an empty workspace because no project is found.)
4. Close all open editors tabs.
5. Exit eclipse.
6. rm -rf org.eclipse.core.resources (Delete the newly created directory.)
7. mv org.eclipse.core.resources.bak/ org.eclipse.core.resources (Restore the original directory.)
8. Start eclipse and start working. :-)

or

eclipse -clean -clearPersistedState

or

open -a Eclipse.app --args -clearPersistedState -clean
