java - 尝试使用 DataflowRunner 时出现 ClassNotFound 异常

Question

我正在尝试使用 Apache Beam 0.6.0 在 GCP 上启动数据流作业。我正在使用 shade 插件编译一个 uber jar，因为我无法使用“mvn:execjava”启 Action 业。我包括这个依赖项:

<dependency>
  <groupId>org.apache.beam</groupId>
  <artifactId>beam-runners-google-cloud-dataflow-java</artifactId>
  <version>0.6.0-SNAPSHOT</version>
</dependency>

我收到以下异常:

Exception in thread "main" java.lang.IllegalArgumentException: Unknown 'runner' specified 'DataflowRunner', supported pipeline runners [DirectRunner]
    at org.apache.beam.sdk.options.PipelineOptionsFactory.parseObjects(PipelineOptionsFactory.java:1609)

    at java.lang.Class.forName(Class.java:264)

我还漏掉了什么吗？

Answer 1

尝试

mvn compile exec:java -Dexec.mainClass=Yourmain Class -Pdataflow-runner

*在最后添加-Pdataflow-runner
