rebar3 fails to fetch and copy dependencies (LFE project)

After some years I'd like to back working with Erlang/LFE. I've a little project I made to learn the language. I'm unable to fetch dependencies using rebar3 get-deps command.

It follows rebar.config, also available here.

{erl_opts, [debug_info, {src_dirs, ["test"]}]}.
{lfe_first_files, []}.
{deps_dir, ["deps"]}.
{eunit_compile_opts, [
   {src_dirs, ["test"]}
  ]}.
{deps, [
   {lfe, "0.9.0", {git, "git://github.com/rvirding/lfe.git", {tag, "v0.9.0"}}},
   {clj, ".*", {git, "git://github.com/lfex/clj.git"}},
   {lhc, ".*", {git, "git://github.com/lfex/lhc.git"}},
   {ljson, ".*", {git, "git@github.com:lfex/ljson.git", "master"}}, 
   {ltest, ".*", {git, "git://github.com/lfex/ltest.git", {tag, "0.4.1"}}}
  ]}.

I know that I've referenced an old version of LFE... But if I remove all deps and try to add them again: the first that fails is clj. However with rebar.config in its original state, I got the following output after rebar3 get-deps. Complete output here.

I checked a similar question and documentation, but I was still unable to fix the problem.

My system is macOS Catalina. It follows Erlang environment versions: ERLANG 22.2.1, LFE 1.3, REBAR3 3.12.0.

All installed with brew. Please let me know if more details are needed.

I would really appreciate any help.

Solution

I finally discovered that referencing lfe/clj and lfe/lhc is redudant, since these packages are indirectly and correctly referenced in implicit way from other ones.

I've removed these from rebar.config, updated to latest syntax and used tag when possible (otherwise master). I switched all URLs to use https:// instead of SSH with scheme git://.

Now I'm able to get dependencies with rebar3 get-deps and compile with rebar3 compile.

Updated rebar.config:

{erl_opts, [debug_info, {src_dirs, ["test"]}]}.
{lfe_first_files, []}.
{deps_dir, ["deps"]}.
{eunit_compile_opts, [
   {src_dirs, ["test"]}
  ]}.
{deps, [
   {lfe, {git, "https://github.com/rvirding/lfe.git", {"tag", "v1.3"}}},
   {ljson, {git, "https://github.com/lfex/ljson.git", "master"}},
   {ltest, {git, "https://github.com/lfex/ltest.git", {tag, "0.9.0"}}}
  ]}.
