Now I don't know where is the issue. I want to use same work space, don't want to create another. Creating new workspace solves this issue, but that is not what I want.

Solution

How i can able to change work space if i am not able to change the workspace? –

You can specify it in the command line:

eclipse.exe -clean -data /path/to/new/workspace

You can modify the eclipse.ini: see FAQ Eclipse

-data 
<workspace-path>

As mentioned in "How to make eclipse refer to workspace in the same folder as exe file?"

Make sure the -data argument appears before any JVM arguments

That way, you don't touch/delete anything from your old workspace, and can still re-import existing projects.
