Ant WsImport2 Fails With java.lang.NoClassDefFoundError:

Question

我已经这样定义了我的 Ant 脚本：

<taskdef name="xjc" classname="com.sun.tools.xjc.XJC2Task">
    <classpath>
        <path refid="extraJars" />
    </classpath> 
</taskdef>

<taskdef name="wsimport" classname="com.sun.tools.ws.ant.WsImport2">
    <classpath>
        <path refid="extraJars" />
    </classpath>
</taskdef>

在 "extraJars" 中，我拥有完成运行任务所需的所有 Jar。喜欢：

jaxb-api-2.3.1.jar
jaxb-impl-2.2.6.jar
jaxb-xjc-2.2.7.jar
jaxws-tools-2.3.2.jar

现在，当我运行脚本时，出现错误：

我做了一些 google，我看到我包含的 class com/sun/istack/localization/LocalizableMessageFactory$ResourceBundleSupplier 存在 jaxb-Impl jar。我检查了 Java2s 网站。你能告诉我它哪里出错了吗，或者我需要一些额外的 JARS 吗？

只是想补充一点，构建文件中的第 740 行是：

 <wsimport wsdl="${build.dir}/src/${wsdl.file}" destdir="build" wsdlLocation="file:/WEB-INF/wsdl/${wsdl.file}" failonerror="true">
        <depends dir="${build.dir}/src" includes="*.xsd" /> 
        <produces dir="${lib.dir}" includes="${webservice.name}${webservice.component}WSBeans.jar"/>
    </wsimport>

Answer 1

我用 JAXB Core Jar 的更新版本修复了它。

失踪的 class 在：

jaxb-core-2.3.0.1.jar

之前，我使用的是：

jaxb-core-2.2.7.jar
