Could not locate ring/util/request__init.class or ring/util/request.clj on classpath

FileNotFoundException 
Could not locate ring/util/request__init.class or ring/util/request.clj on classpath:   
clojure.lang.RT.load (RT.java:443)

This is happening in the leiningen repl when i try to use one my namespaces:

(use 'cmp.repl)

This issue is only happening on my deployment environment (Ubuntu Server 12) but it works fine on my development environment Mac OS 10.8

My project.clj file is as follows:

(defproject cmp "0.1.0-SNAPSHOT"

Solution

  • After running lein deps :tree i found that i had to add an exclusion for ring/ring-core to compojure in the project file as well. Working well for me now
