數據流的 Beam 模板不會上傳到存儲桶

Question

我已經按照所有快速入門/文檔來創建基於 Java 的數據流模板。 我找到並完成的步驟是：

1）創建項目：

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 編譯

這報告構建成功

3）編譯上傳到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"

output 是：

沒有文件上傳到步驟 3 中設置的存儲桶。

有什么問題？

問題出在run()方法上。 取自@gixen 評論：

問題是一件真正的小事，run() 方法從未被觸發
