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, compilation 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?
