we basically need to find a way to build a package from the source.
Not sure how it can be done yet using rebar3. There was a tool for rebar but it can’t be used anymore. Maybe there are already facilities for relx/rebar3.
I will open a ticket asap, imo the first thing is to define our tooling to generate automatically nightly and stable packages. It seems possible to link the CI to packagecloud for example. Thoughts?
