-e -X开关没有显示任何有关此错误的信息。

“主”.jax_ws_commons.jaxws.Invoker.main(Invoker.java:87)：不能在.jax_ws_commons.jaxws.Invoker.main(Invoker.java:87)上转换java.lang.NoSuchMethodError

这是我正在尝试的最基本的配置。

我的配置有什么问题？谢谢你的帮助

Answer 1

根据jaxb xew插件的示例，您需要使用较新版本的jaxws maven插件。该示例使用2.3.1-b03版本，该版本也适用于我的项目。这个插件的旧版本可能是在与jaxb xew插件不兼容的库中编译的。

如果浏览示例代码历史记录，您也会发现jaxws maven插件2.2版的配置。

公地-129的解决方案帮助了我：

    <configuration>
         <vmArgs>
            <vmArg>-Djavax.xml.accessExternalSchema=all</vmArg>
         </vmArgs>
    </configuration>

Answer 3

值得注意的是:我有同样的错误--使用Maven 3.2.2，并将jaxws-maven-plugin设置为2.3。这就停止了对问题的处理：

线程"main“java.lang.ClassCastException中的异常:不能将java.lang.NoSuchMethodError转换为java.lang.Exception

阅读线程和堆栈溢出帖子，似乎使用新版本的插件会有所帮助。一直移动到2.3.1-b01，一直到2.3.1-b03。这使这个问题转变为现在的结果：

java.lang.NoClassDefFoundError: org/sonatype/aether/*由: java.lang.ClassNotFoundException: org.sonatype.aether引起。

似乎在2.3.1-b03与任何Maven发行版(即>=3.1 )一起工作时，都存在一个有很好记录的问题。您可以通过搜索(其中有打开的JIRAs和bug报告)或启动这里来找到更多信息。

最后，我又回到了2.2。对于插件和这个工作没有和问题。
