Compiling Clojure?

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...
