从Jenkins流水线任务test调用new_job时出现属性缺失异常

问题场景 #

在Jenkins中，流水线任务test调用另一个流水线任务new_job并传递变量时出现报错，但两个任务单独运行均正常。

Test任务代码 #

pipeline {
    agent any
    stages {
        stage('Executing First job') {
            steps {
                sh 'echo "Running first job"'
                }
        }
        stage('Running another job') {
             when {
                     equals expected: true, actual: params.deploy2job
             }
             steps {
                  build job: 'new_job', parameters: [string(name: 'abc', value: qa), string(name: 'xyz', value: test)]
             }
         }
    }
}

错误原因 #

报错核心是groovy.lang.MissingPropertyException: No such property: qa for class: groovy.lang.Binding，Groovy解析代码时，将qa和test识别为需要引用的变量，但这两个变量在当前流水线上下文中并未定义。而你实际的需求应该是传递字符串字面量"qa"和"test"。

解决方案 #

将需要传递的字符串值用单引号或双引号包裹，明确告知Groovy这是字符串字面量，而非变量引用：

修改后的流水线代码 #

pipeline {
    agent any
    stages {
        stage('Executing First job') {
            steps {
                sh 'echo "Running first job"'
            }
        }
        stage('Running another job') {
             when {
                     equals expected: true, actual: params.deploy2job
             }
             steps {
                  build job: 'new_job', parameters: [
                      string(name: 'abc', value: 'qa'), 
                      string(name: 'xyz', value: 'test')
                  ]
             }
         }
    }
}

额外说明 #

如果qa和test确实是需要引用的变量（比如流水线参数、环境变量），需要确保变量已正确定义并通过正确的方式引用：

• 若为流水线参数：使用params.qa、params.test
• 若为环境变量：使用env.qa、env.test
