With the following I get a folder called folder under another/source/folder. It's the right place in the hierarchy, but not the right name, it seems to ignore the name property.

     - path: source/folder
        name: ReplacementName
        group: another/source/folder
        createIntermediateGroups: false

If I take out the group property then I get a folder called "ReplacementName" at the root of the project (which is what you'd expect with no group specified).
