Ecplipse ANT-build-Fehler

Ich bin neu mit ANT bauen, und ich habe einen Problem, wenn ich versuche, ich erhalte eine Nachricht:

BUILD FAILED
C:\Users\user\Documents\PM\proyecto-base\proyecto-base\intranet\build.xml:169: Referenz xdoclet.classpath nicht gefunden.

aber ich habe xdoclet.classpath deklariert sind bereits in der gleichen Datei.

Außerdem habe ich die Eigenschaften wie ${xdoclet.lib.dir} deklariert bauen.Eigenschaften-Datei.

hier ist meine build.xml Datei

die Linien, die zurückgekehrt sind mir die Fehlermeldung sind folgende:

    <classpath>
        <path refid="xdoclet.classpath" />
        <path refid="classpath" />
    </classpath>
</taskdef>

aber wie ich Ihnen sagte, ich habe bereits erklärt, meine xdoclet.classpath in der gleichen Datei am Anfang:

 <path id="xdoclet.classpath">
            <fileset dir="${xdoclet.lib.dir}" />
            <pathelement location="${j2ee.jar}" />
            <pathelement location="${servlet.jar}" />
        </path>

Kann Jemand mir mit diesem Problem helfen bitte? vielen Dank
