有没有办法在詹金斯管道中打印昨天的日期？

Question

我需要在我的詹金斯管道之一中使用昨天的日期。

有没有办法在詹金斯管道脚本中打印昨天的日期。

def date = new date()
println date // this is printing the current date 

def date1 = date - 1 or date.minus(1)
println date 1 // This is also printing the current date.

有没有办法在詹金斯管道脚本中获取昨天的日期。

Answer 1

这会起作用的。

def today = new Date()
def yesterday = today - 1
println today.format("MM/dd/yyyy")
println yesterday.format("MM/dd/yyyy")

输出：

03/25/2020 -- Today's date
03/24/2020 -- Yesterday's date

同时如果您的代码如下，

def date = new Date()
println date
def date1 = date - 1
println date1

如果没有格式，它会像这样打印。

Jenkins 声明式管道示例：

#! groovy
pipeline {
  agent any
  stages {
    stage('Build') {
        steps {
            script {
                    def today = new Date()
                    def yesterday = today - 1
                    def daybeforeyesterday = yesterday.previous()
                    println "Today: " + today.format("MM/dd/yyyy") + " && Yesterday: " +
                    yesterday.format("MM/dd/yyyy") + " && The Day before yesterday: " +
                    daybeforeyesterday.format("MM/dd/yyyy")
                } 
            }
        }
    }
}

输出：

[Pipeline] // node
