使用wsimport生成带有ant的toString - ServiceConfigurationError

Question

我使用wsimport任务从.wsdl生成类，我想生成toString方法。我使用的代码是：

<target name="wsimport_v2">
    <taskdef name="wsimport" classname="com.sun.tools.ws.ant.WsImport">
        <classpath>
            <pathelement location="C:\Users\a\Documents\Antin\antifun\lib\jaxws-tools.jar" />
            <pathelement location="C:\Users\a\Documents\Antin\antifun\lib\jaxb2-basics-0.6.0.jar" />
            <pathelement location="C:\Users\a\Documents\Antin\antifun\lib\jaxb2-basics-tools-0.6.0.jar" />
            <pathelement location="C:\Users\a\Documents\Antin\antifun\lib\jaxb2-basics-ant-0.6.0.jar" />
            <pathelement location="C:\Users\a\Documents\Antin\antifun\lib\jaxb2-basics-runtime-0.6.0.jar" />
        </classpath>
    </taskdef>
    <mkdir dir="/tmp" />
    <wsimport wsdl="/src/wsdl/WebSubscriptionService_v_4.3.wsdl" destdir="/tmp" sourcedestdir="C:\Users\a\Documents\Antin\antifun\src\antifun\generated" keep="true" xnocompile="true">
        <xjcArg value="-XtoString"/>
    </wsimport>
</target>

但是我得到了

Buildfile: C:\Users\a584187\Documents\Antin\antifun\build.xml
wsimport_v2:
[wsimport] Consider using <depends>/<produces> so that wsimport won't do unnecessary compilation
