You don't want to set S to this as you're then building things in your
metadata directory. I suspect the code in more recent versions cleans
${S} before fetching/unpacking and this is wiping out your files.

You probably want S = "${WORKDIR}" or maybe S = "${WORKDIR}/hello_2.7",
I can't remember exactly where the fetcher places a directory of files.

Cheers,
