title: Package does not exist in this plugin
body: <p>I tried importing a plugin as a source project in my workspace. Now I am getting a package does not exist in this plugin error in the Manifest.mf file. But the packages do exist in the source folder of the same plugin. What could be the issue? I tried googling but I could find only these kind of errors when the package is coming from a different eclipse project. Pls give me some light on this</p>
