It does work.
As far as I can tell, the namespace with defmethod must require the
namespace with defmulti and also the namespace with defmethod must be
required from some other namespace that is being executed.
Eg:
*foo.clj:*
(ns foo)
(defmulti mmtest identity)
(defmethod mmtest :default [_] (println "default"))
*bar.clj:*
(ns bar
(:require [foo]))
(defmethod mmtest :bar [_] (println "in bar"))
*core.clj:*
(ns core
(:require [foo :refer [mmtest]] ; The mm we want to call
[bar])) ; include the :bar impl
(println "Testing")
(mmtest :bar) ; Prints "in bar"
If you don't require bar from core, it will print default instead.
Note, in this example I require foo and bar from core and use mmtest in
core too - you don't need to require bar from the same namespace that you
use in from like I did here. You just need to make sure that the (defmethod
...) call gets executed before you call mmtest.
