Ah I hadn’t seen @al2o3cr and was gonna suggest something similar:

defmodule ConditionalDependencies do

  if Code.ensure_loaded?(HTTPoison) do
    def hello do
      HTTPoison.start()
      IO.puts("HTTPoison started")
      case HTTPoison.get("https://elixirforum.com/t/conditional-dependencies-in-mix-exs/48468") do
        {:ok, %HTTPoison.Response{status_code: 200} = _data} ->
          IO.puts("It worked")
        _other ->
          IO.puts("HTTP failed")
      end
    end
  else
    def hello do
      IO.puts("No HTTPoison")
    end
  end

end

ConditionalDependencies.hello
