在Jenkins Pipeline DSL中迭代一个常规列表 [英] Iterating a groovy list in Jenkins Pipeline DSL

问题描述

我的Pipeline中有一个简单的groovy列表，它添加了一些映射：

  def componentList = [] 
 
 def componentMapEntry1 = [：] 
 componentMapEntry1 ['componentName'] =Dashboard_Core
 componentList<< componentMapEntry1 
 
 def componentMapEntry2 = [：] 
 componentMapEntry2 ['componentName'] =Dashboard_Equities
 componentList<< componentMapEntry2 
 
 def cme3 = [：] 
 cme3 [componentName] =home
 componentList<< cme3 
  

执行作业时，我验证大小

  echolist of size+ componentList.size（）
  

  [Pipeline] echo 
列表3的大小
  

我可以将它列印出来

  println componentList 
  

...

 [Pipeline] echo 
 [{componentName = Dashboard_Core}，{componentName = Dashboard_Equities}，{componentName = home}] 
  pre> 
 
 
我可以做一个for循环并迭代列表
 
 pre $ code> for（i = 0; i< componentList.size（）; i ++）{
 println componentList [i] 
} 
  

...

  [Pipeline] echo 
 {componentName = Dashboard_Core } 
 [Pipeline] echo 
 {componentName = Dashboard_Equities} 
 [Pipeline] echo 
 {componentName = home} 
  

到目前为止，所有的w埃尔。

问题出现在我尝试使用标准groovy迭代器时：

  componentList.each {
 printlnadded+ it.componentName 
} 
  

在这种情况下，我只获得第一个元素

  [Pipeline] echo 
 added Dashboard_Core 
 
 code> 

为什么我只能在这里得到第一个元素？我试了几次，使用.each（）只能返回第一个元素。当我在groovy命令行运行相同的代码时，它自然会迭代为groovy会期待。是否.each {}函数会被某种方式覆盖？


解决方案

每个 关闭的方法在Pipeline脚本中还不能工作。修复正在进行中。同时为循环使用C风格。

I have a simple groovy list in my Pipeline that adds some maps:

def componentList = []

def componentMapEntry1 = [:]
componentMapEntry1['componentName']="Dashboard_Core"
componentList << componentMapEntry1

def componentMapEntry2 = [:]
componentMapEntry2['componentName']="Dashboard_Equities"
componentList << componentMapEntry2

def cme3 = [:]
cme3["componentName"] = "home"
componentList << cme3

When job is executed, I validate size

echo "size of list "+componentList.size()

...

[Pipeline] echo
size of list 3

I can print it out the list

println componentList

...

[Pipeline] echo
[{componentName=Dashboard_Core}, {componentName=Dashboard_Equities}, {componentName=home}]

I can do a for loop and iterate the list

for (i = 0; i <componentList.size(); i++) {
    println componentList[i]
}

...

[Pipeline] echo
{componentName=Dashboard_Core}
[Pipeline] echo
{componentName=Dashboard_Equities}
[Pipeline] echo
{componentName=home}

So far all's well.

Problem comes in when I try to use standard groovy iterator:

componentList.each {
    println "adding "+it.componentName
}

In this case I only get the first element

[Pipeline] echo
adding Dashboard_Core

Why would I only get the first element here? I've tried this several times and using .each() only seems to return first element. When I run the same code at groovy command line, it naturally iterates as groovy would expect. Is the .each{ } function getting overwritten somehow?

解决方案

The each method on a closure does not yet work in Pipeline script. A fix is in progress. Meanwhile use a C-style for loop.
