Hi, I don't think it is the right way to use interfaces in clojure. Take a look at this <https://medium.com/@ujjawaldixit099/implementing-java-interfaces-in-clojure-3e5f0b80ba14> and this <https://stackoverflow.com/questions/8614734/how-do-i-implement-a-java-interface-in-clojure/8615002> . You could create a java project with the interfaces you need and import that instead.
I think the issue is that this setup requires AOT and it might be missing from your configuration. To fix it try adding this to project.clj file: :profiles {:dev {:aot [ie4clj.api]}} It can be tricky If you want to do lein uberjar and generate a jar file. Alternatively, you can use compile-files <https://clojuredocs.org/clojure.core/*compile-files*> (then you don't need import statement). (note that in your gist you had some errors when defining AndList, I've fixed it) (also take a look at the clojure style guide <https://github.com/bbatsov/clojure-style-guide>, as AndList is not really the way to name things in clojure )) ) (ns ie4clj.api) (definterface Inferrable (^boolean eval []) (^boolean evalMembers [members])) (ns ie4clj.AndList) (when *compile-files* (require 'ie4clj.api)) (def AndList (reify ie4clj.api.Inferrable (eval [_] true) (evalMembers [_ m] true))) Hope this helps, On Sat, 17 Jul 2021 at 21:06, Jack Park <jackp...@topicquests.org> wrote: > I created a gist > https://gist.github.com/KnowledgeGarden/39742ae9ae641f0d8facb31b288ece4c > > which explains a ClassNotFoundException when I am importing and reifying a > particular interface in another clj file. > > It's really baffling because, in the load order, core calls a test in a > test file - getting that to compile landed on the solution of an (:import > ...) statement; once that worked, then the code in that test calls another > file AndList.clj which happens to have several places where it reifies the > same interface.
