Question

我正在尝试将参数传递给脚本管道。通过阅读文档，它应该很简单，但是我一直遇到错误。我在做什么错了？

代码如下：

node("spvlanautomation01.lab.dtcc.com") {
    parameters {
        string(name: 'VLAN', defaultValue: '', description: '')
    }
    stage("Find VLAN File") {
        echo "VLAN is ${params.VLAN}"
    }
}

我尝试过

    echo "VLAN is ${VLAN}"

...而且也不起作用

这是我得到的错误

您已使用声明性管道语法定义了参数。对于脚本化管道，语法为：

properties([
    parameters([
        string(name: 'VLAN', defaultValue: '', description: '')
    ])
])
node("spvlanautomation01.lab.dtcc.com") {
    stage("Find VLAN File") {
        echo "VLAN is ${params.VLAN}"
    }
}

注意：语法properties([ parameters([...]) ])也适用于声明性管道。

无法访问脚本管道中的参数
