I am testing out Clojure/Java interop. I created a new Leiningen project and created this project.clj file with a few dependencies I'll be using:
(defproject kente "0.1.0-SNAPSHOT" :description "FIXME: write description" :url "http://example.com/FIXME" :license {:name "Eclipse Public License" :url "http://www.eclipse.org/legal/epl-v10.html"} :dependencies [[org.clojure/clojure "1.4.0"] [ring/ring-jetty-adapter "1.0.0-RC1"] [compojure "0.6.5"] [hiccup "0.3.7"] [cheshire "5.0.1"]] :java-source-paths ["src/java"] :plugins [[lein-ring "0.8.2"]] :ring {:handler kente.core/application} :main kente.core) I also included the "java-source-paths" list and put a hello.java file into the src/java directory that looks like this:
public class hello { private String msg = "Hello World"; public String sayHello() { return this.msg; } } and then I created this core.clj file from the template:
(ns kente.core (:require [java/hello])) (defn application "I don't do a whole lot." [x] (println x "Hello, World!")) (defn -main [] (application "Say: ")) As you can see, I'm not even using the hello java class in the application function, I'm just requiring it, but I get this stack trace when I run "lein jar" in the terminal:
$ lein jar Compiling kente.core Exception in thread "main" java.io.FileNotFoundException: Could not locate hello__init.class or hello.clj on classpath: , compiling:(core.clj:1) at clojure.lang.Compiler$InvokeExpr.eval(Compiler.java:3387) at clojure.lang.Compiler.compile1(Compiler.java:7035) at clojure.lang.Compiler.compile1(Compiler.java:7025) at clojure.lang.Compiler.compile(Compiler.java:7097) at clojure.lang.RT.compile(RT.java:387) at clojure.lang.RT.load(RT.java:427) at clojure.lang.RT.load(RT.java:400) at clojure.core$load$fn__4890.invoke(core.clj:5415) at clojure.core$load.doInvoke(core.clj:5414) at clojure.lang.RestFn.invoke(RestFn.java:408) at clojure.core$load_one.invoke(core.clj:5227) at clojure.core$compile$fn__4895.invoke(core.clj:5426) at clojure.core$compile.invoke(core.clj:5425) at user$eval7.invoke(NO_SOURCE_FILE:1) at clojure.lang.Compiler.eval(Compiler.java:6511) at clojure.lang.Compiler.eval(Compiler.java:6501) at clojure.lang.Compiler.eval(Compiler.java:6477) at clojure.core$eval.invoke(core.clj:2797) at clojure.main$eval_opt.invoke(main.clj:297) at clojure.main$initialize.invoke(main.clj:316) at clojure.main$null_opt.invoke(main.clj:349) at clojure.main$main.doInvoke(main.clj:427) at clojure.lang.RestFn.invoke(RestFn.java:421) at clojure.lang.Var.invoke(Var.java:419) at clojure.lang.AFn.applyToHelper(AFn.java:163) at clojure.lang.Var.applyTo(Var.java:532) at clojure.main.main(main.java:37) Caused by: java.io.FileNotFoundException: Could not locate hello__init.class or hello.clj on classpath: at clojure.lang.RT.load(RT.java:432) at clojure.lang.RT.load(RT.java:400) at clojure.core$load$fn__4890.invoke(core.clj:5415) at clojure.core$load.doInvoke(core.clj:5414) at clojure.lang.RestFn.invoke(RestFn.java:408) at clojure.core$load_one.invoke(core.clj:5227) at clojure.core$load_lib.doInvoke(core.clj:5264) at clojure.lang.RestFn.applyTo(RestFn.java:142) at clojure.core$apply.invoke(core.clj:603) at clojure.core$load_libs.doInvoke(core.clj:5298) at clojure.lang.RestFn.applyTo(RestFn.java:137) at clojure.core$apply.invoke(core.clj:603) at clojure.core$require.doInvoke(core.clj:5381) at clojure.lang.RestFn.invoke(RestFn.java:408) at kente.core$loading__4784__auto__.invoke(core.clj:1) at clojure.lang.AFn.applyToHelper(AFn.java:159) at clojure.lang.AFn.applyTo(AFn.java:151) at clojure.lang.Compiler$InvokeExpr.eval(Compiler.java:3382) ... 26 more What should I be doing differently?
