ALL MY PROJECTS DISAPPEARED FROM PROJECT EXPLORER OF ECLIPSE 

Solved:
I got this problem (Empty project list) after unusual shutdown of an eclipse. After exploring some time in Google i found the solutions for it.
Here is the steps to overcome this eclipse bug.

Solutions
Close Eclipse.
open your terminal
go to /home/user/workspace/.metadata/.plugins
execute command rm -rf org.eclipse.core.resources(Or remove folder  manually means delete  .eclipse.core.resources Folder)
Start Eclipse
go to File->Import then General->Existing Projects into Workspace
Click the “Select root directory” field and browse to each subfolder in your workspace folder, and import.
