谷歌云数据流上的Apache梁

我试图在谷歌云数据流上运行一项工作，但无法使部署工作。作业运行正常使用DirectRunner但只要我切换到数据流亚军我得到以下异常：谷歌云数据流上的Apache梁

我的命令来运行：

mvn compile exec:java -Dexec.mainClass=my.package.SalesTransactions -Dexec.args="--runner=DataflowRunner --project=my-project --tempLocation=gs://my-project/tmp" -Pdataflow-runner

你可以分享你的pom.xml文件，或者确认你已经添加了对Dataflow runner的依赖吗？ –

我已经添加了一个显示使用的maven配置文件的pom.xml提取。 – jimmy

发现我的错误。当从DirectRunner切换到DataFlowRunner时，我不得不在我的pom.xml中添加依赖关系，而不是将其作为配置文件运行时依赖关系。

<dependency> 
     <groupId>org.apache.beam</groupId> 
     <artifactId>beam-runners-google-cloud-dataflow-java</artifactId> 
     <version>${beam.version}</version> 
    </dependency>
