Projects in Project Browser are disappeared but re

Question

Every new day my projects are lost in project browser in eclipse-indigo but remain in disk, so I must import all projects again in every morning. Do you have any idea about this problem?

I can see all projects in ~/workspace/.metadata/.plugins/org.eclipse.core.resources/.projects

When I open the eclipse, the files which I worked one day ago, make an exception: org.eclipse.core.runtime.CoreException: The file does not exist.

Two days ago my eclipse crashed and this problem started probably after this time. Also I found these in error logs:

--> The workspace exited with unsaved changes in the previous session; refreshing workspace to recover changes.

--> Ignored attempt to add saveable that was already registered

--> Unable to create editor ID org.eclipse.jdt.ui.PropertiesFileEditor: The file does not exist.

Solution: Shut down Eclipse IDE Remove and backup your workspace/.metadata/.plugins/org.eclipse.core.resources directory Start Eclipse IDE (with -clean to be super-safe) Reimport all projects (UPDATE: Just use File->Import->Existing Project into Workspace and browse your workspace/project directory) Enjoy
