Build-time dependencies

[jesperes]

I'm trying to whip an old legacy code base into rebar3 shape, and we have a couple of cases where project apps have some "pre-build" steps they need to do, consisting of calls into the Erlang code of their dependencies. What is the "proper" way to deal with this? I had sort of hopes that there would be some way to do

{deps, [{my_dep_app, ...} ...
{pre_hooks, [{ ... {call, my_dep_app_module, do_pre_build_hook, [arg1, arg2, ...]} ...

Do I need to resort to writing rebar3 plugins if I want to do this sort of stuff?

(Related question: can I have a rebar3 plugin which resides in the project itself where it is used?)

Yes, sounds like you need a plugin.

Sadly you can't have plugins within a project. It would be nice but isn't possible at this time.
