A FileCreationTask is a file task that when used as a dependency will be needed if and only if the file has not been created. Once created, it is not re-triggered if any of its dependencies are newer, nor does trigger any rebuilds of tasks that depend on it whenever it is updated.
Is this file task needed? Yes if it doesn't exist.
