尝试使用DataflowRunner时出现ClassNotFound异常

I'm trying to launch a Dataflow job on GCP using Apache Beam 0.6.0. I am compiling an uber jar using the shade plugin because I cannot launch the job using "mvn:execjava". I'm including this dependency:

我正在尝试使用Apache Beam 0.6.0在GCP上启动Dataflow作业。我正在使用shade插件编译一个超级jar，因为我无法使用“mvn：execjava”启动作业。我包括这种依赖：

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

I am getting the following exception:

我收到以下异常：

Am I missing something else?

我错过了别的什么吗？
