Because you used require. Try clojure.contrib.classpath/classpath instead.
You have the following possibilities to shorten that:
(ns my
(:require [clojure.contrib.classpath :as cp]))
… (cp/classpath) …
or (with :only listing everything you want to import)
(ns my
(:use [clojure.contrib.classpath :only (classpath)]))
… (classpath) …
Both of these are considered clean style. You can also include everything of a
namespace with a pure :use (w/o :only) but be aware that that might do more
than you want.
Sincerely
Meikel
