Groovy腳本中的變量零

Question

我面臨一個非常奇怪的問題

// Update the service
stage "Update Service"
def SERVICE_NAME = "currency-converter-search-srv"
def TASK_FAMILY = "currency-converter-search"
def TASK_REVISION = sh "aws --region us-east-1 ecs describe-task-definition --task-definition currency-converter-search | jq .taskDefinition.revision"
def DESIRED_COUNT = sh "aws --region us-east-1 ecs describe-services --services ${SERVICE_NAME} | jq .services[0].desiredCount"
if (DESIRED_COUNT == 0) {
  DESIRED_COUNT = 1
}
sh "aws --region us-east-1 ecs update-service --cluster default --service ${SERVICE_NAME} --task-definition ${TASK_FAMILY}:${TASK_REVISION} --desired-count ${DESIRED_COUNT}"

此腳本失敗，在日志下方：

[Pipeline] stage (Update Service)

An error occurred (InvalidParameterException) when calling the UpdateService operation: revision must be between 1 and 2147483647
[Pipeline] }

原因是因為TASK_REVISION變量為0但根據其處理方式，它不是零，而是13 。 你知道為什么這種奇怪的行為嗎？

您不能將sh的結果分配給變量。

sh不會返回任何有意義的信息...我認為這是有問題的 ，但是還沒有解決方法

解決方法似乎是將結果重定向到文件，然后讀取該文件
