Scot:
A "fileset that does not exist" is a contradiction
in terms. A fileset, by definition, consists of
existing files accessible from an existing directory.
Nonexistence of the parent directory yields a build
error, as you have seen. If no child files can be
matched by the fileset's (explicit or implicit)
patterns the fileset will be empty (additional
narrowing is accomplished by any nested selectors).
You can, however, use filelists, paths, and
pathelements to compose paths some of whose members do
not exist.
