I have a Docker image that I use to compile my releases for deployment, I recently updated it to use OTP 24 and the latest Elixir version (1.12.0).

After making that change, now my release builds always fail with the following error:

$ MIX_ENV=prod mix release
...

** (Mix) Could not compile dependency :sleeplocks, "/home/sezdocs/.mix/rebar3 bare compile --paths /home/sezdocs/project/endpoints/_build/prod/lib/*/ebin" command failed. You can recompile this dependency with "mix deps.compile sleeplocks", update it with "mix deps.update sleeplocks" or clean it with "mix deps.clean sleeplocks"

Does anyone knows why is this happening and how to solve it?

Also, I don’t know if this helps, but here is my Dockerfile:

I build it with:

docker build --build-arg USER=$USER   \
             --build-arg UID=$(id -u) \
             --build-arg GID=$(id -g) \
             --no-cache               \
             -t tip-off/builder:v1 . 

and run it with:

docker run --detach-keys='ctrl-e,e' -it -v$(pwd):/home/$USER/project --rm tip-off/builder:v1
