@alexmiller the behavior of -R seems a big strange to me, shouldn’t it compose any aliases + your local deps.edn deps?

-R is solely about selecting aliases to be used when resolving deps. The aliases it can select from are those produced by the combined deps.edn files in play, which typically includes your install, user, local deps.edn (and -Sdeps passed on command line)

aliases are not pulled from transitive deps

I’m not sure that would even be possible based on the order in which things are resolved
