EDIT: Other discussions are underway related to this issue on Bukkit forums and on Github .
So, I know that one or two people tried to do this without any luck. But I think I'm almost there.
One problem: I don’t know Java, so for me this is a bit foreign. Anyway..
So, I made a simple class in Clojure as follows:
(ns com.gdude2002.ClojurePlugin.mainclj (:gen-class :name com.gdude2002.ClojurePlugin.mainclj :extends org.bukkit.plugin.java.JavaPlugin) (:import org.bukkit.plugin.java.JavaPlugin)) (defn -onEnable [this] (java.util.logging.Logger/getLogger "Loaded clojure plugin!")) (defn -onDisable [this] (java.util.logging.Logger/getLogger "Unloaded clojure plugin!"))
I am using the clojure compile function to compile this Java class as follows.
(set! *compile-path* ".") (compile 'com.gdude2002.ClojurePlugin.mainclj)
Then I put it in the jar manually, in com / gdude2002 / ClojurePlugin / mainclj.class (as well as inserting plugin.yml in the root directory).
So far so good. This method does not make a bukkit bitch about my code (in particular), which I think is good. Now about the problem.
When I try to start the server with this manual box, I get the following output.
21:43:30 [SEVERE] Could not load 'plugins\plugin.jar' in folder 'plugins' org.bukkit.plugin.InvalidPluginException: java.lang.NoClassDefFoundError: clojure/lang/IFn
"So," I think, "it seems simple enough - he can't find Clojure, right?" So, I put the clojure jar in all kinds of places with the same error. I also add META-INF / MANIFEST.MF to the jar containing Class-Path: ../lib . Still nothing.
So, thinking that I was smart, I pulled out the clojure folder from the clojure banner and ran it in mine, also putting the folder in .. / lib and other places that I thought this might help.
Now I get this error.
21:51:33 [SEVERE] Could not load 'plugins\plugin.jar' in folder 'plugins' org.bukkit.plugin.InvalidPluginException: java.lang.ExceptionInInitializerError ... Caused by: java.io.FileNotFoundException: Could not locate clojure/core__init.class or clojure/core.clj on classpath: ...
The fact is that both of these things exist, as far as I can judge.
EDIT: Decided to show the code of the decompiled class here, in case someone helps.

EDIT: The comments stated that I should publish the project.clj file. The fact is that I do not have it! I run compile.clj on mainclj.clj directly and create jarfile manually.
At this moment, I am completely at a standstill. Anyone have any ideas on this?
