Compiling Clojure?

I'm feeling slightly silly here, but I can't get Clojure Hello World to compile.

Directory structure:

hello-world/
  clojure-1.1.0.jar
  build/
    classes/
  src/
    test/
      hello.clj

hello.clj:

(ns test.hello
  (:gen-class))

(defn -main [& args]
  (println "Hello" (nth args 0)))

Interaction:

$ cd hello-world
[hello-world]$ java -cp ./clojure-1.1.0.jar:./build/classes:./src clojure.main
Clojure 1.1.0
user=> (require 'test.hello)
nil
user=> (test.hello/-main "there")
Hello there
nil
user=> (compile 'test.hello)
java.io.IOException: No such file or directory (hello.clj:2)
user=> *compile-path*
"classes"
user=> (doseq [p (.split (System/getProperty "java.class.path") ":")] (println p))
./clojure-1.1.0.jar
./build/classes
./src
nil

So I can load and call the file from the REPL, but it doesn't compile.

According to clojure.org, compilatio开发者_Go百科n needs

• namespace must match classpath-relative file path - check
• *compile-path* must be on the classpath - check
• :gen-class argument to the ns form - check

I found this post from a year back, as far as I can tell I'm doing exactly the same, but it doesn't work.

What am I missing?

System: OS X 10.6, Java 1.6.0, Clojure 1.1

Got it, there's a fourth requirement:

• *compile-path* is resolved relative to the JVMs working directory, normally the directory where java is started. Or by REPL: (System/getProperty "user.dir"),

So this works:

user=> (set! *compile-path* "build/classes")     
"build/classes"
user=> (compile 'test.hello)
test.hello

Why you don't use Leiningen? It's much easier to use it, than compile code manually. You can use my article about it as introduction...

To run clojure file

clojure filename.clj
