“..:DependentProject” not supported in settings.gradle?

When I put a relative project path with ".." in the settings.gradle file, Eclipse is throwing an error and confusing the ".." for a literal folder I think.

I created a simple GitHub project that recreates this error.

Please refer to this StackOverflow question I posted for all the details.
