Question

import hudson.model.*;
import hudson.AbortException;
import jenkins.model.Jenkins;


@NonCPS
def allNodes = jenkins.model.Jenkins.instance.nodes
def triggerJob = false


for (String  node: allNodes) {
    if ( node.getComputer().isOnline() && node.nodeName == "ABC" ) {
        println node.nodeName + " " + node.getComputer().countBusy() + " " + 
        node.getComputer().isAcceptingTasks()
        triggerJob = true
        break
  }
}

if (triggerJob) {
    println("triggering build as node is available")
    build job: 'jobName', parameters:
        [
            /** list of string Parameters **/
        ]
}

以上作业触发构建，但失败并显示：

发生的异常：在现场hudson.model.Slave.launcher 原因：java.io.NotSerializableException：hudson.slaves.JNLPLauncher

您只能使用在代码中实现Serializable接口的类-Node和Computer都不能实现。为了使用它们，您需要将各自的代码封装在@NonCPS方法中，例如：

import hudson.model.*;
import hudson.AbortException;
import jenkins.model.Jenkins;

@NonCPS
def shallTrigger() {
    def triggerJob = true
    def allNodes = jenkins.model.Jenkins.instance.nodes


    for (String  node: allNodes) {
        if ( node.getComputer().isOnline() && node.nodeName == "ABC" ) {
            println node.nodeName + " " + node.getComputer().countBusy() + " " + 
            node.getComputer().isAcceptingTasks()
            triggerJob = true
            break
        }
    }
}
if (shallTrigger) {
    println("triggering build as node is available")
    build job: 'jobName', parameters:
        [
            /** list of string Parameters **/
        ]
}

无法解决Jenkins NotSerializableException错误
