What is the dependency url?
With
nubank/matcher-combinators {:mvn/version "3.9.2"}
in my deps.edn I can start a repl, but it seems I cant require anything from that.
not sure I got your error, but you use it like https://github.com/editor-code-assistant/eca/blob/ce986ee843d3dfe9fb622507c79502187dec9c86/test/eca/shared_test.clj#L6
