使用mvn命令部署数据流模板时出错

Question

你好，我正在运行下面的代码来部署GCP中的数据流模板。

mvn compile exec:java 
-Dexec.mainClass=com.google.cloud.teleport.templates.TextIOToBigQuery 
-Dexec.cleanupDaemonThreads=false 
[-Dexec.args="--runner=DataflowRunner 
--project=$PROJECT_ID 
--stagingLocation=gs://bucket/staging 
--tempLocation=gs://bucket/temp 
--templateLocation=gs://bucket/templates/writeToBQ.json 
--region=$DEV_REGION
"] 
-P dataflow-runner

但是我一直得到下面的错误…我不确定为什么要把参数作为文件?我只能假设我的命令格式是错误的…任何想法吗?

Answer 1

你能试着从命令中去掉方括号吗?在这里可以找到一个例子。

mvn compile exec:java 
-Dexec.mainClass=com.example.myclass 
-Dexec.args="--runner=DataflowRunner 
--project=PROJECT_ID 
--stagingLocation=gs://BUCKET_NAME/staging 
--templateLocation=gs://BUCKET_NAME/templates/TEMPLATE_NAME 
--region=REGION" 
-P dataflow-runner
