如何打印一个groovy变量？

我有詹金斯管道中下面的代码：如何打印一个groovy变量？

stage ('Question') { 
    try { 
     timeout(time: 1, unit: 'MINUTES') { 
      userInput = input message: 'Choose server to publish to:', ok: '', parameters: [ 
       [$class: 'hudson.model.ChoiceParameterDefinition', choices: 'pc-ensureint\nother-server', description: 'Choose server to publish to:', name: 'server'] 
     ] 
     } 
    } catch (err) { 
     userInput = [server: 'pc-ensureint'] // if an error is caught set this value 
    } 
} 

node() { 
    println ${server} 
}

我试图与在“ChoiceParameterDefinition”设置“服务器”变量来解决问题。

当我运行构建，我得到以下错误：

据我所知，“服务器”是一个时髦的变量，因此我应该能够使用$来访问它{}。

所以我已经试过：

echo ${server} 
print ${server} 
println ${server} 
println "${server}"

但无论我怎么努力我不断收到此错误。

任何想法我做错了什么？

它应该只与'println“$ {server}”'或者'println server'一起工作 – Opal

但是它不会......否则我不会问这个问题... –

下面的代码为我工作：

echo userInput

还适用于通用webhook触发器插件和管道作业 – JRichardsz

看看堆栈跟踪。我认为它是课堂上的美元。变量是注意到$定义常规

我还没有定义它与$ ...你有没有读过这个问题？ –

$ class：'hudson.model.ChoiceParameterDefinition'我的意思是这是导致错误。看起来不正确 – Torsten

这是正确的方式来设置hudson.model.ChoiceParameterDefinition –

你不应该使用${varName}当你字符串之外，你应该只使用varName。在你使用它的内部字符串像这样; echo "this is a string ${someVariable}";。事实上，你可以在${...}中放置一个通用的java表达式; echo "this is a string ${func(arg1, arg2)}。
