数据流的 Beam 模板不会上传到存储桶

Question

I've followed all the quickstarts/documentation for creating Java-based dataflow templates.我已经按照所有快速入门/文档来创建基于 Java 的数据流模板。 The steps I've found and done is:我找到并完成的步骤是：

1) Create the project: 1）创建项目：

mvn archetype:generate \
      -DarchetypeGroupId=org.apache.beam \
      -DarchetypeArtifactId=beam-sdks-java-maven-archetypes-examples \
      -DarchetypeVersion=2.22.0 \
      -DgroupId=com.example \
      -DartifactId=JsonToBucket \
      -Dversion="0.1" \
      -Dpackage=com.example.dataflow \
      -DinteractiveMode=false

2) mvn clean && mvn compile 2) mvn clean && mvn 编译

This reports build success这报告构建成功

3) Compile and upload to bucket 3）编译上传到bucket

mvn compile exec:java -Pdataflow-runner \                      
-Dexec.mainClass=com.example.dataflow.JsonToBucket -Dexec.cleanupDaemonThreads=false  \   
-Dexec.args="--runner=DataflowRunner \
--project=PROJECT \
--stagingLocation=gs://some-bucket/staging \
--templateLocation=gs://some-bucket/beam_templates/DisruptivePubSubToBucket"

The output of this is: output 是：

No files are uploaded to the bucket set in step 3.没有文件上传到步骤 3 中设置的存储桶。

What could be wrong?有什么问题？

Answer 1

The issue was with the run() method.问题出在run()方法上。 Taken from @gixen comment:取自@gixen 评论：

The problem was a real small thing, the run() method was never triggered问题是一件真正的小事，run() 方法从未被触发
