Working with Rebar3

[yenrabbyui]

I'm trying to get the ssl example running using rebar3 and have an issue popping up. I've moved the src and priv directories into my rebar3 app called "junk." I've also updated the dependencies to cowboy 2.9.0. Any ideas would be appreciated as I'm stuck.

There error is
exited: {bad_return, {{junk_app,start,[normal,[]]}, {'EXIT', {noproc, {gen_server,call, [ranch_sup, {start_child, {{ranch_listener_sup,https}, {ranch_listener_sup,start_link, [https,ranch_ssl, #{connection_type => supervisor, socket_opts => [{next_protocols_advertised, [<<"h2">>,<<"http/1.1">>]}, {alpn_preferred_protocols,[<<"h2">>,<<"http/1.1">>]}, {port,443}, {cacertfile, "/home/pseudo/junk/_build/default/lib/junk/priv/ssl/cowboy-ca.crt"}, {certfile, "/home/pseudo/junk/_build/default/lib/junk/priv/ssl/server.crt"}, {keyfile, "/home/pseudo/junk/_build/default/lib/junk/priv/ssl/server.key"}]}, cowboy_tls, #{connection_type => supervisor, env => #{dispatch => [{'_',[],[{[],[],toppage_h,[]}]}]}}]}, permanent,infinity,supervisor, [ranch_listener_sup]}}, infinity]}}}}} type: temporary

Well it seems you haven't started Cowboy. With Rebar3 you will probably need to add cowboy to the .app.src file.
