Unable to build a simple project with clojure-ant-tasks
Ivan Chernetsky
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?

Hmmm ... This builds fine for me (with the inclusion of <namespace>edn.main</namespace> in the <compile-clojure /> element). I've uploaded what I have here so you can try it on your machine:
http://github.com/jmcconnell/test-clojure-ant-project/tree/master
What versions of Clojure and Clojure-Contrib are you using? The Ant task currently only supports Clojure 1.0, because I had to choose between supporting clojure.contrib.test and clojure.test and I thought there would be more interest in a 1.0-compatible version. I'd be happy to revisit that decision if there's interest.
Also, which version of Ant?

It seems to be identical.

The freshest ones.

ivan@inote edn-extract % ant -version
Apache Ant version 1.7.1 compiled on August 29 2009
Here is the debug output: http://pastebin.com/m6306a855
I have just tried "ant -lib lib" and everithing's ok.
ivan@inote edn-extract % java -cp lib/clojure.jar:edn-extractor.jar
edn.main "Big Brother"
Hello Big Brother!
I'm curious what may be the reason!

This appears to be the problem. If I use the HEAD version of Clojure, I get the same error and it goes away if I use the -lib argument.
The Ant tasks have only been tested against Clojure 1.0, since I assumed that's what most people would be using in a production context. I am thinking about going the Contrib route and tagging a 1.0-compatible version and updating everything to work against HEAD. Feel free to watch the repo on GitHub if you'd be interested in that.

Me too ... I wonder what the difference could be that it works with the -lib argument and not without it. There was a change to clojure.lang.RT.baseLoader() after 1.0 that could be playing a role here. Thanks for pointing it out.

For my personal projects the HEAD version is stable enough. :)

OK, thank you!
