Hi all! I’m getting a warning-
Poison.decode!/2 defined in application :poison is used by the current application but the current application does not depend on :poison. To fix this, you must do one of:
1. If :poison is part of Erlang/Elixir, you must include it under :extra_applications inside "def application" in your mix.exs
2. If :poison is a dependency, make sure it is listed under "def deps" in your mix.exs
3. In case you don't want to add a requirement to :poison, you may optionally skip this warning by adding [xref: [exclude: [Poison]]] to your "def project" in mix.exs
I’ve seen some similar issues and solutions proposed elsewhere on this forum, but they don’t seem to solve it for me. I have an internal mock server for API function testing… maybe I’ve got something screwed up in my mix file!
My relevant mix.exs snippet
def application do
[
extra_applications: [:logger],
mod: {TruckSched.Application, [env: Mix.env()]},
applications: applications(Mix.env())
]
end
defp applications(:test), do: applications(:default) ++ [:cowboy, :plug]
defp applications(_), do: [:httpoison]
# Run "mix help deps" to learn about dependencies.
defp deps do
[
{:httpoison, "~> 2.0"},
{:poison, "~> 5.0"},
{:plug_cowboy, "~> 2.6"},
{:mix_test_watch, "~> 1.0", only: :dev, runtime: false}
]
end
end
Versions if helpful-
elixir 1.13.4-otp-25
erlang 25.0.3
Thanks for any help!
