Re: Importing gen-class classes from one namespace into another, like Java?

[Ryan Cole]

I forgot to mention, I also tried replacing the dashes with underscores, in the import namespace in the core.clj file. Same error.

I'm basically writing a jar to be used entirely from a Java application, in Clojure. I don't know if it's better to just use Java for this yet, or not. I'm experimenting, though.

I've got every namespace in my Clojure project compiling using AOT. In one namespace, I use gen-class to create a class. In another namespace, I need to create an instance of that class. Do I have to import that class like I would Java classes? I've tried several methods and I keep getting class not found exceptions.

Below is my pretty basic code:

core.clj

(ns com.rycole.bukkit-plugin.core

  (:import [com.rycole.bukkit-plugin.listeners PlayerLoginListener])

  (:gen-class :name com.rycole.bukkit-plugin.core.Main

              :extends org.bukkit.plugin.java.JavaPlugin))

(defn -onEnable [this]

  (.info (.getLogger this) "PLUGIN ENABLED")

  (.registerEvents (.getPluginManager (.getServer this)) (com.rycole.bukkit-plugin.listeners.PlayerLoginListener.) this))

(defn -onDisable [this]

  (.info (.getLogger this) "PLUGIN DISABLED"))

listeners.clj

(ns com.rycole.bukkit-plugin.listeners

  (:gen-class :name com.rycole.bukkit-plugin.listeners.PlayerLoginListener

              :implements org.bukkit.event.Listener

              :methods [[^{org.bukkit.event.EventHandler true} onPlayerLoggedIn [org.bukkit.event.PlayerLoginEvent] void]]))

(defn -onPlayerLoggedIn [this evnt]

  (.info (.getLogger this) "PLAYER LOGGED IN"))

Hi,

you have to add a (:require com.rycole.bukkit-plugin.listeners) before
you import the class. And you have to replace dashes with underscores
on import.

Kind regards
