I'm using kondo in a cljs/cljc project that uses clojure.test.check.random for generating https://github.com/dgtized/shimmers/blob/master/src/shimmers/math/deterministic_random.cljc#L1. However recently I started seeing line errors for unresolved var on make-random, split, and rand-double. When I look at the upstream library it does look like the implementations are not split in a cljc file but actually implemented as separate https://github.com/clojure/test.check/blob/master/src/main/clojure/clojure/test/check/random.cljs and https://github.com/clojure/test.check/blob/master/src/main/clojure/clojure/test/check/random.clj file implementations. I'm assuming that's why they are marked as unresolved vars but am curious what the correct way to reference these from a cljc file without triggering an unresolved var warning?
As context, I do use this library locally in both a cljs project and as a dependency for a clj project, so the code does work, I'm just curious why it's triggering a warning and how one is supposed to mark it correctly to resolve it in this case.
are you able to make a repro using a public github repo that I can clone locally with some instructions on how to reproduce the issue?
Yea the warning shows up when I run kondo on the https://github.com/dgtized/shimmers repo that the deterministic-random file is in and that's public, just check it out and run bin/lint on it and it triggers the warning.

linting took 6411ms, errors: 0, warnings: 3Is there a cache somewhere I can clean maybe?
yes, .clj-kondo/.cache you can clean
I'll try the project in my editor with lsp to see if I can get it to repro
huh, well after cleaning the cache it's not reporting the unused var anymore, so I guess that fixes my problem. Curious that you are seeing those warnings though, as I'm not seeing those. Thank you very much!
no I can't
it's not "unused var", but "unresolved var"
Sorry, yes unresolved var, that was just a typo on my part.
Very much appreciate you taking the time to check it out personally, sorry it was just a cache issue, next time I will try that first before asking!
no worries. there could be a bug somewhere in clj-kondo that's just hard to repro, but glad it's working now
