我需要连接到具有相互身份验证安全策略的Web服务。
因此，我在maven java项目中的WSO2 Developer Studio 3.1.0中创建了一个存根客户端。 我的项目使用maven来管理我的依赖项，所以我包含了所需的库以使客户端工作，但我发现了一个有趣的问题。
如果我按照这个顺序放置这个neethi依赖项，那么一切正常：
<dependency>
<groupId>org.apache.neethi.wso2</groupId>
<artifactId>neethi</artifactId>
<version>2.0.4.wso2v4</version>
</dependency>
<dependency>
<groupId>org.apache.neethi</groupId>
<artifactId>neethi</artifactId>
<version>3.0.2</version>
</dependency>
如果我更改了订单，我发现了这个错误：

我的问题是我需要在jar文件中打包这个实现，所以我在Eclipse STS中创建了一个可运行的jar文件但是当我运行jar时我看到了这个错误： 注意：如果我删除3.0.2 neethi依赖项，我的eclipse项目工作正常，但jar不行，下面有相同的错误。

关于解决这个问题的任何想法??
感谢。
