    Hello Bhanu,
    Can u plz let us know which plugin project r u trying to create, so that we can help u better.

    This sometimes happens when the path u had given for that plugin has been changed, check that properly.

    try deleting the eclipse and not the workspace and install it again,sometimes this works out, i know this is not the correct solution.
    To finish sooner, take your own time....
