I have an app with the following structure: mix.exs lib |_my_app.ex |_mix/tasks/my_mix_task.ex The file lib/my_app.ex defines a module MyApp with a function load. The mix/tasks/my_mix_task.ex includes defmodule Mix.Tasks.MyApp.MyTask do use Mix.Task def run(_) do Mix.Task.run("app.s…

I’m an idiot who should RTFM : For instance, archives do not include dependencies, as those would conflict with any dependency in a Mix project after the archive is installed.

Have you tried putting this inside the project function inside mix.exs? elixirc_paths: ["lib"],
