pipeline如下：

def skipRemainingStages = false   //是否跳过生产部署
def timeout_mins = 5 //超时时间，单位分
def input_message   //提示语
def randomToken    //发布秘钥
def skipadminUser = false
 
 
//系统个人信息
def Applier_id
def Applier_name
def Applier_mail
 
pipeline{
    agent {
		label "java_agent"
	}
    options { //调用颜色插件
        ansiColor('xterm')
        skipDefaultCheckout(true)
    }

       Applier_name = ""
