Why is deps.get called?

[tsloughter]

In testing I noticed that mix deps.get is called here https://github.com/Supersonido/rebar_mix/blob/master/src/rebar_mix_utils.erl#L138 which results in a bunch of deps being fetched under _build/default/lib/<elixir app>/deps

Why is this the case? They aren't used are they, they aren't built at least so they must not be?

I can send a PR to remove it unless there is a reason it needs to be done.

Ok, a lot more is coming clear, like the protocol consolidation hook removal, now that I've looked at this function that calls deps.get, it also changes how compile is called. Why is it no longer:

    AppDir = rebar_app_info:dir(AppInfo),
    case sh("elixir -pa \"../*/ebin\" -S mix compile --no-load-deps "
                        "--no-deps-check --no-protocol-consolidation",
                        [{cd, AppDir},
                         {return_on_error, true},
                         {use_stdout, true},
                         {env, [{"MIX_BUILD_PATH", filename:join(AppDir, "../../")},
                                {"MIX_ENV", "prod"}]}]) of
        {error, {127, _}} ->
            {error, {mix_not_found, rebar_app_info:name(AppInfo)}};
        {error, {_Code, Error}} ->
            {error, {mix_compile_failed, rebar_app_info:name(AppInfo), Error}};
        _ ->
            ok
    end.
