如何在声明性Jenkins管道的各个阶段之间传递变量？

如果要使用文件（由于脚本是生成所需值的东西），则可以

readFile

如下所示使用。如果没有，请使用如下所示

sh

的

script

选项：

// Define a groovy global variable, myVar.// A local, def myVar = 'initial_value', didn't work for me.// Your mileage may vary.// Defining the variable here maybe adds a bit of clarity,// showing that it is intended to be used across multiple stages.myVar = 'initial_value'pipeline {  agent { label 'docker' }  stages {    stage('one') {      steps {        echo "${myVar}" // prints 'initial_value'        sh 'echo hotness > myfile.txt'        script {          // OPTION 1: set variable by reading from file.          // FYI, trim removes leading and trailing whitespace from the string          myVar = readFile('myfile.txt').trim()          // OPTION 2: set variable by grabbing output from script          myVar = sh(script: 'echo hotness', returnStdout: true).trim()        }        echo "${myVar}" // prints 'hotness'      }    }    stage('two') {      steps {        echo "${myVar}" // prints 'hotness'      }    }    // this stage is skipped due to the when expression, so nothing is printed    stage('three') {      when {        expression { myVar != 'hotness' }      }      steps {        echo "three: ${myVar}"      }    }  }}
