My Eclipse (Juno) was working fine till yesterday, it’s not initializing today. It doesn’t even showing any error message! Splash screen coming and GONE!

Solution:

Step 1: Delete YOUR_WORKSPACE\.metadata\.plugins\org.eclipse.core.resources\.snap

If your problem is not solved yet

STEP 2: DELETE
YOUR_WORKSPACE\.metadata\.plugins\org.eclipse.e4.workbench\workbench.xmi

You are DONE!
