我试图从Spring XD shell运行Groovy脚本。但脚本不会触发

Question

我正在尝试使用groovy脚本将数据从SQL SERVER提取到HDFS。 流定义部署流，部署后不会获取脚本。

流定义：

stream create --name WhatIFScenarioRun --definition "trigger --initialDelay=10 --fixedDelay=30 | script --script=file:/opt/spring-xd-1.3.1.RELEASE/xd/modules/processor/scripts/WhatIF.groovy | log" --deploy
