No valid version ([]) of .app file found

[auror]

Hello guys,

OS: Mac OSX

Erlang/OTP 23 [erts-11.1.8] [source] [64-bit] [smp:16:16] [ds:16:16:10] [async-threads:1] [hipe] [dtrace]

IEx 1.11.3 (compiled with Erlang/OTP 23)

We're using rebar_mix to use Elixir dependencies inside our rebar3 project. There's a problem while generating a release

===> Compiling oauth
Consolidating 13 implementations of protocol Elixir.Jason.Encoder
===> [relup_helper] running gen_appups
===> Assembling release myapp...
===> Error generating release:
jason: No valid version ([]) of .app file found. Found file "/Users/YYYYYY/Programs/myapp/_build/myapp/rel/myapp/lib/jason-/ebin/jason.app" with version "1.2.2"

make: *** [myapp] Error 1

jason is the transitive dependency and added to the rebar.config deps

    {jason, {git, "git@github.com:michalmuskala/jason.git", {tag, "v1.2.2"}}}

Although, the next attempt seems to be solving it..

$ make
===> Compiling oauth
Consolidating 13 implementations of protocol Elixir.Jason.Encoder
===> [relup_helper] running gen_appups
===> Assembling release myapp...
===> Release successfully assembled: _build/myapp/rel/myapp

Not sure what's happening here.. Please let us know if you need more information !

Hello @Supersonido / @tsloughter , now i've been getting another crash while releasing...

Error: function_clause

Notice the name, which has been reversed ?

"-nosaj/bil/ppaym/ler/ppaym/dliub_/ppaym/smargorP/YYYYYY/sresU/"

What could be happening here ?

Regards

[ferd]

it's trying to add a version to the end of the filepath and failing because it's a binary instead of a list. I can't recall if that was patched in rebar3 (try a newer version) or judged to be a problem with the dep, or just not addressed yet

[auror]

We're checking this on rebar3 3.14.3.

[tsloughter]

Can you check if the jason.app file has a binary for vsn.

[auror]

@tsloughter Hmmm it's a string.

              {registered,[]},
              {vsn,"1.2.2"}]}.

The vsns for apps are usually UTF-8 strings i believe !

[zmstone]

the vsn suffix is appended correctly if we revert this commit: https://github.com/erlang/rebar3/commit/80671df57a06915a23493b9fc721d1ae8f493964

[zmstone]

and the workaround is to run rebar3 as profile do compile,release instead of rebar3 as profile release

[zmstone]

This does not seem to be an issue of rebar_mix. Rather something to improve in rebar3 (maybe?) so I created https://github.com/erlang/rebar3/pull/2518
