Hello Christopher, I will try to address exactly your example, with Counterclockwise, and hopefully you'll get the general view of how to do things on the go.
So you want to instanciate a new namespace like this : (ns play.xml-example (:require [clojure.zip :as zip] [clojure.data.zip :as zf] [clojure.xml :as xml]) (:use clojure.data.zip.xml)) Code be taken from examples on the web generally have a lot of assumptions. Here, for instance, the assumption was that clojure.data.zip namespace is already in the classpath, and for this to happen, it should either be shipped with the clojure library (which it isn't), or installed in the classpath via one of the declared dependencies of your project. A small search of the String "clojure.data.zip" in Google directs me to https://github.com/clojure/data.zip/ (2d search entry for me, but this could vary for you) This page is the README for project "clojure.data.zip", with a "Releases and Dependency Information" section. This section contains : Leiningen dependency information: [org.clojure/data.zip "0.1.1"] There we are: you need the artifact named data.zip (member of the artifacts group named org.clojure). Its current stable version is 0.1.1. Those artifact id + group id + version are called "coordinates" in Leiningen. Leiningen inherits this terminology from Maven (http://www.apache.org) which is a Java project management / build tools with which Leiningen shares the way to store / retrieve "artifacts" from Internet. The easiest way to continue from here, if you already have Eclipse + Counterclockwise installed, is to just create a new Clojure project by following CCW's documentation for creating a new project ( https://github.com/laurentpetit/ccw/blob/master/doc/src/main/asciidoc/documentation.adoc#create-a-new-project ) In the `Package Explorer View` (by default opened on the left side of the editors) you should see your project. Open the project's file `project.clj`, it should look like this: project.clj ---- (defproject foo "0.1.0-SNAPSHOT" :description "FIXME: write description" :url "http://example.com/FIXME"; :license {:name "Eclipse Public License" :url "http://www.eclipse.org/legal/epl-v10.html"} :dependencies [[org.clojure/clojure "1.5.1"]]) ---- You should also see inside your project a node named `Leiningen Dependencies`. If you expand it, you should see the clojure jar (`clojure-1.5.1.jar`) Add the dependency for `clojure.data.zip` so that it then looks like this: project.clj ---- (defproject foo "0.1.0-SNAPSHOT" :description "FIXME: write description" :url "http://example.com/FIXME"; :license {:name "Eclipse Public License" :url "http://www.eclipse.org/legal/epl-v10.html"} :dependencies [[org.clojure/clojure "1.5.1"] [org.clojure/data.zip "0.1.1"]]) ; <1> ---- <1> Addition of the clojure.data.zip dependency Save the `project.clj` file. Eclipse will work a little bit in the background to fetch the dependency from Internet (and the next times, from a hidden cached location in `~/.m2/repository`). And then you should see inside the `Leiningen Dependencies` project node a new entry: `data.zip-0.1.1.jar` Now is time to start a REPL and play : in your project's contextual menu, select `Run as > Clojure Application`. A REPL will open, you'll be able to paste the namespace declaration into it ( Ctrl + Enter to send for evaluation): ---- ;; Clojure 1.5.1 => (ns play.xml-example (:require [clojure.zip :as zip] [clojure.data.zip :as zf] [clojure.xml :as xml]) (:use clojure.data.zip.xml)) nil ---- HTH, -- Laurent 2013/10/18 Christopher Bird <seabir...@gmail.com>: > I know this is a pretty old thread, but my questions are quite > similar/related, so I figured here would be a good place for them. > > I am seriously struggling with both the Eclipse/Kepler-CounterClockwise > version in general and the command prompt versions of lein. > My major issue is how to tell the environments which libraries, etc. to > load.
