Unable to build a simple project with clojure-ant-tasks

[Ivan Chernetsky]

Hello!

I wrote build.xml with the following content:

<project name="edn-extractor" default="jar">
  <property name="src.dir" location="src" />
  <property name="classes.dir" location="classes" />
  <property name="jar.name" value="edn-extractor.jar" />

  <path id="project.classpath">
    <pathelement location="${src.dir}" />
    <pathelement location="${classes.dir}" />
    <fileset dir="lib">
      <include name="**/*.jar" />
    </fileset>
  </path>

  <target name="clean" description="Remove generated files.">
    <delete dir="${classes.dir}" />
    <delete file="${jar.name}" />
  </target>

  <target name="def-tasks">
    <taskdef name="compile-clojure"
             classname="com.ubermensch.ant.clojure.CompileTask"
             
classpath="lib/clojure.jar:lib/clojure-contrib.jar:lib/clojure-ant-tasks.jar"
/>
  </target>

  <target name="compile" depends="def-tasks">
    <mkdir dir="${classes.dir}" />
    <compile-clojure>
      <classpath>
        <path refid="project.classpath" />
      </classpath>
    </compile-clojure>
  </target>

  <target name="jar" depends="compile">
    <jar jarfile="${jar.name}" basedir="${classes.dir}">
      <fileset dir="${src.dir}">
        <include name="**/*.clj" />
      </fileset>
    </jar>
  </target>
</project>

And I have a simple directory structure:

# find .
./build.xml
./src
./src/edn
./src/edn/main.clj
./lib
./lib/clojure-contrib.jar
./lib/clojure.jar
./lib/clojure-ant-tasks.jar

Here is the content of main.clj:

(ns edn.main
  (:gen-class))

(defn -main
  [greetee]
  (println (str "Hello " greetee "!")))

Then if I run ant, I get:

Buildfile: build.xml

def-tasks:

Either of clojure/core.clj and clojure/core__init.class is on
classpath, I think. What am I doing wrong?
