Working with elixir dependencies for an escript

[Tobias Pfeiffer]

👋

Me again. So, say - is there a way to make this work with an escript/rebar3 escriptize (Dislaimer: I might also be using escript wrong).

I used rebar3 to create an escript project: https://github.com/PragTob/benchee_erlang_try

Now generating the script failed:

tobi@speedy ~/github/benchee_erlang $ ./_build/default/bin/benchee_erlang 
escript: exception error: undefined function 'Elixir.Benchee':run/1
  in function  benchee_erlang:main/1 (/home/tobi/github/benchee_erlang/_build/default/lib/benchee_erlang/src/benchee_erlang.erl, line 16)
  in call from escript:run/2 (escript.erl, line 757)
  in call from escript:start/1 (escript.erl, line 277)
  in call from init:start_em/1 
  in call from init:do_boot/3 

Of course, though! Haven't added benchee to the applications. But when I add benchee to the applications this happens:

tobi@speedy ~/github/benchee_erlang $ DEBUG=1 rebar3 escriptize
# lots of stuff that I'll spare you...

Seems it doesn't like the transitive elixir dependency there?

Thanks a lot!
