Note:
当我的 Jenkins 环境中只有一个主节点时，我发布了这个问题。这使得序列化成为一个较小的问题，因为没有其他节点可以通信，因此这里的代码不会在多节点环境上按预期运行（例如，readFile只会从主节点读取文件）。
根据我的经验，最好以其他格式（JSON、YAML、Groovy，Jenkins 原生支持）编写配置，或使用外部工具（例如xmllint在 Linux 上）如果您无法控制文件的格式。
原问题：
我有一个 XML 文件，我想将其用作管道脚本的输入。问题是 XMLParser 不可序列化，因此我将其放入 NonCPS 函数中，但因此丢失了 Node 对象。
这是管道脚本：
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
}
这是一个输入示例：
<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：

</branch>
[Pipeline] }
[Pipeline] // node

我正在使用 Jenkins 2.7 和 pipeline 2.1，这是目前最新的。
您可以使用 XmlSlurper，它对我有用。
def xmlText = new XmlSlurper().parse(MyURL)
