How to tell rebar to check for deps in another directory prior to downloading them?

Question

My Erlang project has two folders for applications, lib (with my own apps) and deps (with those defined in rebar.config to be fetched from git). One of the deps (let's call it A) has itself a dep (let's call it B). But I have my own, modified version of B residing in lib.

When I run get-deps, rebar downloads A (as it should), and then recursively looks for its deps, downloading B. Is there a way for rebar to know that I already have a version of B in lib, so it doesn't go and fetch it anew into deps?

Answer 1

you can fork A, and fix deps in rebar.config in the forked A that it points to your version of B.

And setup your project to use forked version of A
