Structuring Clojure cake build environment - clojure

Question

I have a clojure application called mr1; its project.clj is located in ./mr1/, and mr1.clj is located in ./mr1/src.
I cannot figure out how to structure the directories, namespace, and project.clj file correctly, so I can build a binary using cake bin.
Enclosed are my current project.clj and the head and tail of mr1.clj.
src/mr1.clj loads fine into cake repl and executes. cake bin produces an mr1 file that contains no -main.
(defproject mr1 "0.0.1-SNAPSHOT"
:description "TODO: add summary of your project"
:dependencies [[org.clojure/clojure "1.3.0"]
[org.clojure/tools.cli "0.1.0"]]
:main mr1)
(ns mr1
(:use [clojure.string :only [split]]
[clojure.string :only [join]]))
.
.
.
(defn -main
[& args]
(do
(reset! grid-dim (prompt-for-grid-dim))
(reset! mr1-pos (prompt-for-rover-pos 1))
(let [moves (prompt-for-rover-moves)]
(execute-each-move moves #mr1-pos))
(reset! mr2-pos (prompt-for-rover-pos 2))
(let [moves (prompt-for-rover-moves)]
(execute-each-move moves #mr2-pos))
)
)

As I mentioned in answer to your first question, you have to enable AOT-compilation of your namespace. I've copied that answer here in case if someone would have same problem.
As sample.project.clj file says, :main key should have as an assigned value a namespace which contains -main function. So you should have such function
(defn -main [& args]
(do-things-you-want-to-do-on-program-start))
in your mr1.clj. Also AFAIR if you want to use your program as a standalone jar you have to have this namespace gen-classed. By this I mean that you have to:
Include :gen-class option in your namespace definition like this:
(ns mr1
(:gen-class)
...other options...)
Make the namespace AOT-compiled (AOT stands for Ahead Of Time). To do this you need to specify your namespace in the list of AOT-compiled namespaces in project.clj:
(defproject mr1 "0.0.1-SNAPSHOT"
...other definitions...
:aot [mr1]
:main mr1)
After you've done this, you can use cake to generate executable jar for you.
