Question

我正在为我的项目测试一些Jenkins管道命令，并且使用when命令时遇到了问题。

我正在使用Jenkins 2.19，使用此命令时出现不支持的DSL命令错误。

node{
  stage('Hello'){
    when{
        isUnix()
    }
    echo 'Hello'
  }
}

错误：

我的詹金斯版本是否不足以支持这样的命令？我还没有发现任何与支持的命令相关的版本限制。

Answer 1

when命令是Declarative Pipeline syntax的一部分;它不适用于脚本管道。

Scripted Pipeline中的粗略等价物是：

node {
  stage('Hello') {
    if (isUnix()) {
      echo 'Hello'
    }
  }
}

Answer 2

node{
  stage('Hello'){
          isUnix()
          echo 'Hello'
                }
    }

以上代码应该有效。

话虽如此，Declarative管道和Scripted管道之间存在很多差异。一个关键的区别是语法用法。＆＃39;当＆＃39;和＆＃39; isUnix（）＆＃39;命令可能/不可以齐头并进。例如，请参考this link了解如何使用＆＃39;何时使用＆＃39;命令。而且，我不确定＆＃39;何时＆＃39; command可用于返回布尔输出的函数。＆＃39; IsUnix（）＆＃39;总是产生布尔输出（默认输出为true）。
