Compile clojure source into class (AOT) from command line (without using lein)

I am trying to compile the clojure source file into a class file and only run it using the command line, without lein or (possibly) an answer.

I have core.clj in a directory src/hello.

.
└── src
    └── hello
        └── core.clj

This is the source code.

(ns hello.core)
(defn -main
  "This should be pretty simple."
  []
  (println "Hello, World!"))

using (compile)in REPL.

From the hint on this site ( http://clojure.org/compilation ) I tried to get the class file from REPL.

I started REPL with lein replin the src directory and then tried to compile to get an error message.

user=> (compile 'hello.core)

CompilerException java.io.IOException: No such file or directory, compiling:(hello/core.clj:1:1)

Command line

clojure.clj .class/.jar clojure, , clojure REPL.
