我使用以下pom文件创建了Jar。

maven命令

mvn clean
mvn compile
mvn package

Jar命令执行

 java -jar XXXXXX-jar-with-dependencies.jar
      --runner=DataflowRunner
      --jobName=XXXXXXXXXX 
      --project=XXXXXXXXXX 
      --network=XXXXXXXXXX
      --subnetwork=XXXXXXXXXXXX 
      --workerMachineType=XXXXXXX 
      --region=XXXXXXXXXX 
      --maxNumWorkers=XXX 
      --stagingLocation=XXXXXXXXXX 
      --tempLocation=XXXXXXXXXXXX
      --dataflowJobFile=XXXXXXXXXX

发生以下错误

java.lang.IllegalArgumentException: Unknown 'runner' specified 'DataflowRunner', supported pipeline runners [DirectRunner]
at org.apache.beam.sdk.options.PipelineOptionsFactory.parseObjects(PipelineOptionsFactory.java:1615)

作为上述错误的解决方法，我们将以下内容添加到pom文件中，并仅在测试时使用DirectRunner。

    <dependency>
        <groupId>org.apache.beam</groupId>
        <artifactId>beam-runners-direct-java</artifactId>
        <version>2.1.0</version>
        <scope>test</scope>
    </dependency>

使用上述解决方法执行时，发生以下错误。

作为上述错误的解决方法，setCoder已设置，但结果不会更改。

在SDK 1.9.0中，我们可以使用maven创建可执行的Jar。

如果可以创建Jar，你能给我一些如何更改pom文件以及如何运行jar的提示吗？

您是否尝试过包含beam-runners-google-cloud-dataflow-java依赖项？
