Using Jarbundler with ant

I am trying to use jarbundler to generate an .app file with ant. But I am getting the following error:

taskdef class net.sourceforge.jarbundler.JarBundler cannot be found using the AntClassLoader [/Users/Ida/NetBeansProjects/supernova/build/classes/lib/jarbundler-core-3.3.0.jar]

My build.xml file looks like this:

 <path id="classpath">
        <fileset dir="dist/lib">
            <include name="*.jar"/>
        </fileset>
    </path>

    <target name="clean">
        <delete dir="build"/>
    </target>

    <target name="compile">
        <mkdir dir="build/classes"/>
        <javac srcdir="src" destdir="build/classes">
            <classpath>
                <path refid="classpath"/>
                <path location="${jar.dir}/${ant.project.name}.jar"/>
            </classpath>
        </javac>
        <copy todir="build/classes">
            <fileset dir="src" excludes="**/*.java"/>
        </copy>
    </target>

    <target name="dist">
        <mkdir dir="build/classes/lib"/>
        <copy flatten="true" todir="build/classes/lib" includeemptydirs="false">
            <fileset dir="dist/lib">
                <include name="*.jar"/>
            </fileset>
        </copy>
        <mkdir dir="build/jar"/>
        <jar destfile="build/jar/SuperNova.jar" basedir="build/classes">
            <fileset dir="dist/lib">
                <include name="*.jar"/>
            </fileset>
            <manifest>
                <attribute name="Main-Class" value="com.lumenradio.supernova.SuperNovaApp"/>
            </manifest>
        </jar>
    </target>

    <target name="jar">
        <mkdir dir="build/jar"/>
        <jar destfile="build/jar/SuperNova.jar" basedir="build/classes">
            <fileset dir="dist/lib">
                <include name="*.jar"/>
            </fileset>
            <manifest>
                <attribute name="Main-Class" value="com.lumenradio.supernova.SuperNovaApp"/>
            </manifest>
        </jar>
    </target>

    <target name="run" depends="jar">
        <java fork="true" classname="com.lumenradio.supernova.SuperNovaApp">
            <classpath>
                <path refid="classpath"/>
                <path location="build/jar/SuperNova.jar"/>
            </classpath>
        </java>
    </target>



    <target name='package-app'>
        <taskdef name="jarbundler" classname="net.sourceforge.jarbundler.JarBundler">
            <classpath>
                <pathelement location="build/classes/lib/jarbundler-core-3.3.0.jar"/>
            </classpath>
        </taskdef>
        <jarbundler dir="dist" name="SuperNova" 
            mainclass="com.lumenradio.supernova.SuperNovaApp"
            jar="build/jar/SuperNova.jar"/>
    </target>

Anyone now why I am getting this error and how to solve it?

EDIT

Thank you for your help. Now I can create the .app file, but when I try to run it I get the following error:

Error: Could not find or load main class com.lumenradio.supernova.SuperNovaApp

Now my goal looks like this:

<target name='package-app'>
        <taskdef name="jarbundler" classpath="build/classes/lib/jarbundler-core-3.3.0.jar" 
        classname="com.ultramixer.jarbundler.JarBundler"/>

        <jarbundler dir="dist" name="SuperNova" 
            jar="build/jar/SuperNova.jar"
            mainclass="com.lumenradio.supernova.SuperNovaApp"
            icon="SuperNova copy.icns"
            stubfile="universalJavaApplicationStub"
            useJavaXKey="true"
            jvmversion="1.7+"/>
    </target>

I downloaded the jar to have a look and I think the problem is yours classname

is wrong. The JarBundler class is in com.ultramixer.jarbundler.JarBundler

, so try this instead:

    <taskdef name="jarbundler" classname="com.ultramixer.jarbundler.JarBundler">
        <classpath>
            <pathelement location="build/classes/lib/jarbundler-core-3.3.0.jar"/>
        </classpath>
    </taskdef>


Also, since you are only loading one library, there is no need to use a nested classpath instead of an attribute taskdef

classpath

, so you can simplify it a bit:

    <taskdef
        name="jarbundler"
        classname="com.ultramixer.jarbundler.JarBundler"
        classpath="build/classes/lib/jarbundler-core-3.3.0.jar"
    />

The problem was that the lib folder was not in the jar destination, so I solved it by editing the hole build.xml file so it looks like this:

<target name='package-app' depends='clean, jar'>
    <taskdef name="jarbundler" classpath="dist/lib/jarbundler-core-3.3.0.jar" 
    classname="com.ultramixer.jarbundler.JarBundler"/>

    <jarbundler dir="dist" name="SuperNova" 
        jar="dist/SuperNova.jar"
        mainclass="com.lumenradio.supernova.SuperNovaApp"
        icon="SuperNova copy.icns"
        stubfile="universalJavaApplicationStub"
        useJavaXKey="true"
        jvmversion="1.7+"/>

    <mkdir dir="dist/SuperNova.app/Contents/Resources/Java/lib"/>
    <copy flatten="true" todir="dist/SuperNova.app/Contents/Resources/Java/lib" includeemptydirs="false">
        <fileset dir="dist/lib">
            <include name="*.jar"/>
        </fileset>
    </copy>
</target>


It works fine now.
