In the last days I have been trying to track down how error output works with clojure spec. These are my findings so far.
I am using tools.deps and have the following deps.edn file:
{:paths ["src/clj" "resources"]
:deps {
org.clojure/clojure {:mvn/version "1.10.1"},
org.clojure/spec.alpha {:mvn/version "0.2.176"},
org.immutant/web {:mvn/version "2.1.10"}}
