Not easily, no[1]. There are several issues filed against rebar to do
with the way it decides which dependencies to download. They're
hopefully being resolved in rebar3, but -- in my testing at least --
it's not mature yet.

The way I've done it is to have a rebar.deps.config at the top level
which lists the dependencies that I'd like to force -- and lists
nothing else. Then I "rebar -C rebar.deps.config get-deps && rebar
get-deps"; this causes rebar to download the forced dependencies, and
then to use its normal logic. Since the dependencies are already in
the deps/ directory by this point, it doesn't download them again.

Cheers,
Roger.
