在运行Flex模板NoclassDeffoundError时：org/apache/beam/sdk/transforms/dofn
我正在数据流中运行GCP Flex模板。
从模板开始工作时，我会得到以下例外：
Error: Unable to initialize main class.
com.mycompany.pubsubdfjobs.protocol1_0.PubSubRedis
由：java.lang.noclassdeffounderror：org/apache/beam/beam/sdk/transforms/dofn
dofn在项目中的许多类中使用。我可以在本地运行代码。所有依赖项都在我的gradle.build文件中。 gradle.build文件被复制到DokerFile中，用于模板。 有什么问题？
I am running gcp flex templates in dataflow.
While starting a job from a template I am getting this exception:
Error: Unable to initialize main class.
com.mycompany.pubsubdfjobs.protocol1_0.PubSubRedis
Caused by: java.lang.NoClassDefFoundError: org/apache/beam/sdk/transforms/DoFn
DoFn is used in a lot of classes in the Project. I am able to run the code locally. All dependencies are in my gradle.build file. The gradle.build file is copied to the Dokerfile the is used for the template.
What could be the issue?

错误指出您的
jar无法找到项目的主类。该类应根据 documentation，应根据pom.xml文件在您的pom.xml文件上指定。 。该文件需要与文档中列出的样本具有相同的结构。您可以确保插件在pom.xml文件上标记文件与文档中的文件匹配。The error states that your
JARis not able to find the main class for your project. This class should be specified on your pom.xml file according to the documentation. This file needs to have the same structure as the sample presented in the documentation. You can make sure that theplugintag on yourpom.xmlfile matches the one found in the documentation.
