我正在使用Jenkins“Extensible Choice”插件，以便使用AWS RDS数据库实例名称列表填充参数 .
在“Choice provider”中，我选择了“System groovy choice parameter” .
这是groovy代码，它应该返回DB的列表：
//Create buffer to capture command's Standard Out
def sout = new StringBuffer(), serr = new StringBuffer()
//Define here the shell command you would like to execute
def proc = 'aws rds describe-db-instances | grep DBInstanceIdentifier | grep -v Read | awk "{print \$2}" | sed "s/\"//g"'.execute()
//Capture command output into buffer
proc.consumeProcessOutput(sout, serr)
//Time to wait for command to complete
proc.waitForOrKill(1000)
//Converts command output to a list of choices, split by whitespace
return sout.tokenize()
如果我在shell中运行命令，我会正确获得输出：
[ec2-user@jenkins.company.com ~]$ aws rds describe-db-instances | grep DBInstanceIdentifier | grep -v Read | awk "{print \$2}" | sed "s/\"//g"
company
company-dev-70-mysql
dev-rds-2017-10-02
company-check-woocommerce
prod
但是当我运行该作业时，下拉菜单保持为空 .
知道我做错了什么吗？

第二个是 StringBuilder 而不是Buffer .
def sout = new StringBuffer（），serr = new StringBuilder（）
