I'm very confused by what you mean by this. If I do the following, I
get a new random value every time I run it, which does not seem to
match what you are saying:
That's interesting... Hadn't thought of using delay. A user on
Stackoverflow (kotarak) suggested using alter-var-root. This method
will also support setting values for command line arguments.

Here's one way:
(def version (delay (... read the JAR ...))
(defn get-version [] (force version))

This is literally the way we "think"...but if we all verbalized it this
way... we would all have a stack overflow at runtime.

- Why not make the jar available at compile time as well? (e.g. maven
scope="provided")
- You could also use a delay:
(def *version* (delay (get-version)))
and then write @*version* when you want the version information at runtime.
- Equivalently, you could memoize get-version and just call tha
Won't work. The "def" gets executed at compile time, before the JAR
file exists.

Yes. I does not work. The "def" gets evaluated at compile-time, not
run-time. The JAR file that the code is reading does not exist until
after the program is compiled.

Is there a reason why you can't (def version ...) directly, without
calling it via a set-version function?
