我创建了一个maven项目来执行管道。如果我运行main类，管道工作得很好。如果我创建一个胖jar并执行它，我会有两个不同的错误，一个是在Windows下执行，另一个是在Linux下执行

在Windows下：

我该怎么办？

此评论解决了我的问题：

您是否尝试将DataflowRunner的Apache Beam工件显式添加到pom.xml中安德鲁

在这里添加第二个答案，可以更广泛地解决这个问题。 我有一种预感，S.M.将依赖项提取到上面pom文件的顶层的方法恰好绕过了不将shade
ServiceResourceTransformer
与
ManifestResourceTransformer
结合使用的问题

然而，没有看到S.M.的最终pom文件，我不能确定

无论如何，我已经包括了对我有用的shade build插件配置：

  • 我让它在Windows和Linux上工作
    • 

    根据Linux环境提供的堆栈跟踪，您似乎没有提供有效的GCS路径：
    '/home/USER/gs:/MY_BUCKET/temp/staging/'
    。不知何故，应用程序正在用户主目录的根目录中查找路径。你有任何迹象表明为什么会这样吗？您是否尝试将DataflowRunner的Apache Beam工件显式添加到
    pom.xml
    ？谢谢！将google cloud dataflow java sdk全部替换为其所有apache beam依赖项，解决我的问题@S.M.您包含了什么版本的google云数据流java sdk所有依赖项？版本2.2.0？@Max是的，正如您从我的pom.xml中所看到的，我以前包含了版本2.2.0，但我使用beam Runner google cloud dataflow java和其他apache beam依赖项解决了我的问题。您能在这里发布生成的/完整的pom吗？
