How to add directory to Clojure's classpath?

I have installed the libraries with Maven to the ~/.m2/repository/ directory. I would like to add that path to the default Clojure classpath. I could not find the documentation how to do that.

Any hints?

Cheers!

clj
Clojure 1.4.0
user=> (require '[clojure.java.jmx :as jmx])
FileNotFoundException Could not locate clojure/java/jmx__init.class or clojure/java/jmx.clj on classpath:   clojure.lang.RT.load (RT.java:432)

The class path by default is:

user=> (println (seq (.getURLs (java.lang.ClassLoader/getSystemClassLoader))))
(#<URL file:/Users/myuser/cljmx/> #<URL file:/usr/local/Cellar/clojure/1.4.0/clojure-1.4.0.jar> #<URL file:/Users/myuser/cljmx/>)
nil
Solution

  • The non-painful, popular method is to not mess with maven and classpaths and the JRE directly and use leiningen: https://github.com/technomancy/leiningen/

    Otherwise, you can modify whatever is in clj and add/set the classpath in whatever ways java likes. See for example Setting multiple jars in java classpath
