Can't import a java library from a repository in lein project

Question

So, I've made a new project using lein new app bot . Then, I've added a repository and a dependency from it to project.clj :

:dependencies [[org.clojure/clojure "1.8.0"]
               [net.dv8tion/JDA "2.2.0_334"]]
:repositories [["jcenter" {:url "http://jcenter.bintray.com"}]]

That worked. But I can't import it inside a clojure file, none of those work (I tried adding a single quote before class name ( import 'net.dv8tion.jda ) and lowercase jda as well!):

; 1
(ns bot.core
  (:gen-class) (:import net.dv8tion.JDA))
; 2
(ns bot.core
  (:gen-class))
(import net.dv8tion.JDA)

Whole error:

I heard something about java-source-paths , but how do I find what path should I put?

Answer 1

I can't find such class there. I believe you meant net.dv8tion.jda.JDA .
