protected booleansupportsNonFileResources()
Whether this task can deal with non-file resources.

This implementation returns true only if this task is <gzip>. Any subclass of this class that also wants to support non-file resources needs to override this method. We need to do so for backwards compatibility reasons since we can't expect subclasses to support resources.

return
true if this case supports non file resources.
