Jenkins Scripted Pipeline触发Pipeline B失败问题求助

问题场景 #

使用Jenkins Scripted Pipeline，希望在Pipeline A执行成功后触发Pipeline B，编写了如下代码：

stage('Invoke Another Pipeline'){
            steps {
                script{
                    if (params.name == value1 && params.env==prod ){
                        build job: pipelineB-name, propagate: true, wait: true, parameters: [                 string(name: 'param1', value: 'value1')]
                    }
                }
            }
        }

运行后出现错误：

预期Pipeline B能被正常触发。

错误原因分析 #

核心问题是字符串常量未被正确包裹：

• value1、prod是需要匹配的字符串值，但代码中直接以变量名形式书写，Groovy会尝试查找名为value1、prod的变量，而这些变量并未定义，因此抛出MissingPropertyException。
• pipelineB-name是目标流水线的名称，同样需要用引号包裹，否则Groovy会将其解析为pipelineB减去name的表达式，导致语法错误。

修复后的代码 #

将所有字符串常量用单引号（或双引号）包裹，修正后的代码如下：

stage('Invoke Another Pipeline') {
    steps {
        script {
            if (params.name == 'value1' && params.env == 'prod') {
                build job: 'pipelineB-name', 
                      propagate: true, 
                      wait: true, 
                      parameters: [
                          string(name: 'param1', value: 'value1')
                      ]
            }
        }
    }
}

关键修正点 #

1. 给value1、prod、pipelineB-name添加单引号，明确它们是字符串常量而非变量。
2. 调整代码格式，让参数列表更清晰易读，便于后续维护。
