Downloading only a file with multiple methods

: I want to use multimethods to send and distribute functions in multiple files. one of the files contains only multimethods, and to make them usable, I have to manually upload the file. Is there a way to automatically upload a file, rather than explicitly upload it?

here is a simple example of what i am doing:

; app/core.clj
(ns app.core
  (:use [app.fruit.core :only [make-fruit]])
(println (:name (make-fruit :banana)))

; app/fruit/core.clj
(ns app.fruit.core)
(defmulti make-fruit identity)

; app/fruit/banana.clj
(ns app.fruit.banana
  (:use [app.fruit.core :only [make-fruit]])
(defmethod make-fruit :banana [fruit]
  {:name "banana" :color "yellow})

The fruit.banana method does not load unless I explicitly load it into app.core, for example, adding it to the: use group. this seems to have surpassed the goal of using the multidimensional method, since I still have to be explicit in relation to all methods of its implementation.
