解析Jenkins管道中的XML文件 [英] Parsing an XML file within a Jenkins pipeline

问题描述

我有一个XML文件，我想用它作为管道脚本的输入。问题是XMLParser不是可序列化的，所以我把它放在NonCPS函数中，但是我因此丢失了Node对象。

这是管道脚本： p>

  def buildPlanPath ='C：\\buildPlan_test.xml'
 
 @NonCPS 
 groovy.util.Node getBuildPlan（path）{
 new XmlParser（）。parseText（readFile（path））
} 
 
 node {
 // def buildPlan = new XmlParser（）。parseText（readFile（buildPlanPath））
 groovy.util.Node buildPlan = getBuildPlan（buildPlanPath）
 $ b println buildPlan.getClass（）
 println buildPlan 
 println buildPlan.branch 
} 
  

这是一个输入样本：

 < branch name ='mybranch'> 
< stage> 
< job name ='job11'/> 
< job name ='job12'/> 
< / stage> 
< stage> 
< job name ='job21'/> 
< job name ='job22'/> 
< job name ='job23'/> 
< / stage> 
< stage> 
< job name ='job31'/> 
< / stage> 
< / branch> 
  

这是结果：

<$ p $用户管理员
[Pipeline]节点
在C：\Jenkins\workspace\pipeline- develop
[Pipeline] {
[Pipeline] readFile
[Pipeline] echo
class java.lang.String
[Pipeline] echo
< branch name ='mybranch'>
< stage>
< job name ='job11'/>
< job name ='job12'/>
< / stage>
< stage>
< job name ='job21'/>
< job name ='job22'/>
< job name ='job23'/>
< / stage>
< stage>
< job name ='job31'/>
< / stage>
< / branch>
[Pipeline]}
[Pipeline] //节点
[Pipeline]流水线结束

我使用的是管道2.1的Jenkins 2.7，它是目前最新的。

解决方案

认为我的方法是错误的：我决定将XML文件转换为单独的groovy脚本并加载它减少了管道

I have an XML file which I'd like to use as input for a pipeline script. Problem is the XMLParser isn't serializable so I put it in a NonCPS function, but I lost the Node object because of that.

This is the pipeline script:

def buildPlanPath = 'C:\\buildPlan_test.xml'

@NonCPS
groovy.util.Node getBuildPlan(path) {
    new XmlParser().parseText(readFile(path))
}

node {
    //def buildPlan = new XmlParser().parseText(readFile(buildPlanPath))
    groovy.util.Node buildPlan = getBuildPlan(buildPlanPath)

    println buildPlan.getClass()
    println buildPlan
    println buildPlan.branch
}

This is an input sample:

<branch name='mybranch'>
    <stage>
        <job name='job11' />
        <job name='job12' />
    </stage>
    <stage>
        <job name='job21' />
        <job name='job22' />
        <job name='job23' />
    </stage>
    <stage>
        <job name='job31' />
    </stage>
</branch>

This is the result:

Started by user admin
[Pipeline] node
Running on master in C:\Jenkins\workspace\pipeline-develop
[Pipeline] {
[Pipeline] readFile
[Pipeline] echo
class java.lang.String
[Pipeline] echo

    <job name='job11' />
    <job name='job12' />
  </stage>
  <stage>
    <job name='job21' />
    <job name='job22' />
    <job name='job23' />
  </stage>
  <stage>
    <job name='job31' />
  </stage>
</branch>
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline

Finished: FAILURE

I'm using Jenkins 2.7 with pipeline 2.1, which are currently the latest.

解决方案

In the end I think my approach was wrong: I decided to convert the XML file into a separate groovy script and load it within the pipeline
