Eclipse "workspace in is use"

Today again I spent an hour to find the solution for this frequent occuring problem for which I already knew the solution.

AW if while starting the eclipse, one gets "wrokspace is in use" error then try following:

1) run eclipse with -clean option.
eclipse -clean

2) If step one does not solve the problem then try to delete .lock file avaiable in /.metadata/.lock

3) If neither works then open the Task Manager (Ctrl + Shift + Esc), terminate the eclipse(if running) and javaw processes and the go to step two.

If still it does not solve the problem then log a bug with eclipse with complete log.

And if you find any other solution to fix this problem then do reply me.
