Comment faire pour que 'cake repl' fonctionne sous OSX? (J'obtiens 'Exception dans le fil "main" java.lang.NoClassDefFoundError: clojure/main')

Question

J'essaye d'obtenir clojure/emacs/swank/cake tous travaillant ensemble. Selon assembla j'ai besoin de 'cake repl' pour lancer un repl, mais je continue d'obtenir une NoClassDefFoundError. Une idée de comment réparer ça?

Voici ce que je reçois dans la ligne de commande:

$ cake ps

Answer 1

Il s'avère que c'était un problème avec Clojure et Java 1.5. Le correctif sur OS X consistait à utiliser /Applications/Utilities/Java Preferences.app pour passer à Java 1.6.

Answer 2

On dirait que votre projet gâteau par défaut n'a pas le pot de Clojure. Essayez d'exécuter cake deps force.
