Question

I am trying to go through the process of creating a jar file from a simple clojure file. Below is my clojure code:

(ns app.first (:gen-class))  
(refer 'clojure.core)  
(defn -main [& args] (println "this program worked!"))  

I am using these instructions to create the jar file: http://en.wikibooks.org/wiki/Clojure_Programming/Tutorials_and_Tips

I see the error “java.io.FileNotFoundException: Could not locate app/hello__init.class or app/hello.clj on classpath: (NO_SOURCE_FILE:0)” when I try to complete the (compile 'app.first) step.

The only difference between my attempt and the link is the name of my file (first.clj instead of hello.clj).

Can anyone see where I am going wrong? Or for that matter, all I want to do is learn how to create a jar from a clojure file, so if anyone knows of a better/easier way to do that, let me know.

It’s better to use Leiningen for such tasks – it allows to maintain dependencies, and packs all necessary components into jar file
