Error: Path for project must have only one segment

Even Though google shows 995,000 pages containg the text “Path for project must have only one segment” – None of them really explains what this error mean – Except if you look at the source code of WorkspaceRoot class, particularly ‘getProject’ method:

This problem usually occurs when you try to access a project name/path,etc, when it is not avialable or you might have forget to instantiate the IProject object or try to instantiate the IProject with different name.

Solution: Have a look at your code where you are calling

getProject.

Check names, paths are called correctly.
