Finding and using clojure.contrib.string

Question

I have CounterClockwise for Eclipse and believe clojure.contrib should be installed. However, I can't seem to use it or any of the subfiles such as clojure.contrib.string. If I type as I get the following errors

If I type (require 'clojure-contrib.string) I get:

FileNotFoundException Could not locate clojure_contrib/string__init.class or clojure_contrib/string.clj on classpath: clojure.lang.RT.load (RT.java:443)

Long ago in an internet far far away Clojure had a large utility library called clojure.contrib which turned out to be rather hard to maintain, so it was broken up into many libraries, each of which uses the Clojure contributors agreement. In this process clojure.contrib.string became just clojure.string and the names of all the other projects changed and they are released independently now. Seeing references to clojure.contrib is a sign that you are looking at outdated documentation. Also watch out for tutorials that make references to installing Clojure or installing dependencies without leiningen.
