Unable to run test with asdf and system elixir

[fuelen]

Hello

Thank you for this awesome adapter.
I'm trying to integrate it into my workflow and here is the error I've found.
Steps to reproduce:

• install elixir, erlang and asdf

• $ asdf global elixir system
  

• $ asdf global erlang system
  

• try to run some test using neotest plugin
• the test is failed and output is the following

** (SyntaxError) /home/artur/.asdf/shims/mix:3:18: syntax error before: '.'
    |
  3 | exec /home/artur/.asdf/bin/asdf exec "mix" "$@" # asdf_allow: ' asdf '
    |                  ^
    (elixir 1.14.0) lib/code.ex:1245: Code.require_file/2

everything is OK if I specify elixir version from asdf and not the system one.

Tests are run using elixir -S mix ... and not mix .... The first one executes elixir, which finds mix in path and executes it as an Elixir script. But with asdf, mix is a shell script, so it fails to compile.

Somehow, when you use a version from asdf, elixir resolves mix to the real script and not the shim, so it has no issues. I think this is a bug in asdf. You can even run elixir -S mix in a shell and see the same error.

Try opening an issue in the asdf-elixir repo.

Yes, you're right. I see there is a similar issue there which is currently open. I'll close this one for now.
