Jenkins流水线审批输入无法在后续阶段生效问题排查

你遇到的问题根源在于：当input步骤同时指定了parameters和submitterParameter时，返回的结果是一个Map对象（包含ApprovalStatus和approverID两个键值对），而不是单纯的审批状态字符串。你现在直接用env.approvalStatus == 'Approved'做判断，本质是把整个Map和字符串比较，结果必然为false，导致后续阶段全部被跳过。

有两种修复方式，推荐第一种，逻辑更清晰：

方式1：提取审批状态字符串到环境变量 #

修改Approval阶段的代码，先接收input返回的Map，再从中提取ApprovalStatus字段的值赋值给env.approvalStatus：

stage('Approval') {
    steps {
        script {
            emailext body: "Localities : ${Localities} \n name : ${name} \n Click this link to approve and run the executor job: ${env.BUILD_URL}console",
                     subject: "Job Approval: Supplier Delete with build #${currentBuild.number}",
                     to: 'user1'
            timeout(time: 1, unit: 'HOURS') {
                // 先接收完整的审批结果Map
                def approvalResult = input message: 'You want to approve this build? ', ok: 'Submit', parameters: [choice(choices: ['Approved', 'Rejected'], name: 'ApprovalStatus')], submitter: 'user1,user2', submitterParameter: 'approverID'
                // 提取审批状态赋值给环境变量
                env.approvalStatus = approvalResult.ApprovalStatus
                // 可选：保存提交者ID到环境变量
                env.approverID = approvalResult.approverID
            }
        }
        echo "Approval status: ${env.approvalStatus}"
        // 现在会打印：Approval status: Approved
    }
}

这样后续Build和Deploy阶段的when判断就能正常生效。

方式2：直接在when判断中读取Map字段 #

如果不想修改Approval阶段的赋值逻辑，可以直接在when的表达式里从Map中读取ApprovalStatus字段：

stage('Build') {
    when {
        expression { env.approvalStatus?.ApprovalStatus == 'Approved' }
    }
    steps {
        sh 'echo "Building..."'
    }
}
stage('Deploy') {
    when {
        expression { env.approvalStatus?.ApprovalStatus == 'Approved' }
    }
    steps {
        sh 'echo "Deploying..."'
    }
}

?.是Groovy的安全导航运算符，避免Map为null时抛出空指针异常。

agent any
    parameters {
        string(name: 'Localities', defaultValue: '', description: 'Enter Country Name')
        string(name: 'name', defaultValue: '', description: 'Enter  Name')
        string(name: 'HOST', defaultValue: '', description: 'Enter Host Name')
    }
    stages {
        stage('Approval') {
            steps {
                script {
                    emailext body: "Localities : ${Localities} \n name : ${name} \n Click this link to approve and run the executor job: ${env.BUILD_URL}console",
                             subject: "Job Approval: Supplier Delete with build #${currentBuild.number}",
                             to: 'user1'
                    timeout(time: 1, unit: 'HOURS') {
                        def approvalResult = input message: 'You want to approve this build? ', ok: 'Submit', parameters: [choice(choices: ['Approved', 'Rejected'], name: 'ApprovalStatus')], submitter: 'user1,user2', submitterParameter: 'approverID'
                        env.approvalStatus = approvalResult.ApprovalStatus
                    }
                }
                echo "Approval status: ${env.approvalStatus}"
            }
        }
        stage('Build') {
            when {
                expression { env.approvalStatus == 'Approved' }
            }
            steps {
                sh 'echo "Building..."'
            }
        }
        stage('Deploy') {
            when {
                expression { env.approvalStatus == 'Approved' }
            }
            steps {
                sh 'echo "Deploying..."'
            }
        }
    }
}
