json - 如何读取 Json 文件中的变量？

问题描述

我想在 groovy 管道中读取我的 JSON 文件中的变量（app3.path_version）。

任何人都可以帮忙吗？

谢谢

Jenkins_Variables.json：

{
    "app1": {
        "path_version"         : "2.5.0",
        "version"              : "21",
        "install_version"      : "no",
        "report_integration"   : "yes"
    },
    "app2": {
        "path_version"         : "2.1.4",
        "version"              : "20",
        "install_version"      : "no",
        "report_integration"   : "yes"
    },
    "app3": {
        "path_version"         : "2.1.4",
        "version"              : "20",
        "install_version"      : "no",
        "report_integration"   : "yes"
    },
    "app4": {
        "path_version"         : "2.1.4",
        "version"              : "20",
        "install_version"      : "no",
        "report_integration"   : "yes"
    }
}

管道：

pipeline {
   agent any

   environment {
        def variables = readJSON file: 'Jenkins_Variables.json'
   }
   stages {
      stage('Hello') {
         steps {
            echo 'Hello World'
            echo "${variables.app3.path_version}"
            //echo "${variables}"
            }
      }
      stage('Run tests') {
         steps {
            echo 'Run tests'
         }
      }
   }
}

我收到以下错误：

解决方案

从指令中删除def声明environment并将其保存script在管道文件的指令中。如下所示。

pipeline {
   agent any
   stages {
        stage('Read JSON') {
            steps {
                script {
                    echo 'Hello World'
                    def variables = readJSON file: "./Jenkins_Variables.json"
                    echo "${variables.app3.path_version}"
                }
            } 
        }
        stage('Run tests') {
           steps {
              echo 'Run tests'
           }
        }
    }
}
