Hvordan laver man ANT foreach tasks

Nå jeg fandt selv ud af det. Det jeg skulle bruge var ant-contrib-0.6.jar, og så ser min kode således ud, hvor jeg pakker alle subfoldere af en folder i hver deres .jar fil:
  <target name="jarLanguages" description="packs the language files into language specific .jar files">
    <property name="languagepath" value="${ecw.basedir}\languages"/>


    <foreach  param="jar.folder" target="makeFolderJar">

      <path id="base.path">

            <dirset dir="${languagepath}">
              <exclude name="**/help"/>
              <exclude name="**/images"/>
              <exclude name="**/META-INF"/>
              <exclude name="**/JavaHelpSearch"/>

              <exclude name="${languagepath}"/>
            </dirset>

      </path>




    </foreach>

    <delete failonerror="false"  file="${ecw.basedir}\languages\languages.jar"/>



  </target>

  <target name="makeFolderJar" description="jar's the files in the folder that is passed as a parameter to this method under the name jar.folder">
      <echo>jarfolder = ${jar.folder}</echo>
    <basename file="${jar.folder}" property="jar.name"/>
    <echo>jarname = ${jar.name}</echo>

    <antcall target="jarFolderContent">
      <param name="jar.file.name" value="${module.ecw.basedir}/languages/${jar.name}.jar"/>
      <param name="jar.file.content" value="${jar.folder}"/>
    </antcall>
  </target>

og så skal man også lige have denne linie i sin build.xml fil
  <taskdef resource="net/sf/antcontrib/antcontrib.properties"/>
