带有循环电子邮件的 Jenkinsfile 在第一次迭代时失败

Question

使用最新的 Jenkins。

编辑：完整 Java 异常的 pastebin - https://pastebin.com/zZDNj18E

目标：遍历所有节点，检查离线，为每个离线节点发送电子邮件警报。（也尝试了 emailext 警报，无法使用 "offline"）

失败：我的 jenkinsfile 运行完美，没有电子邮件。对于 for 循环中的电子邮件或在函数中单独定义的电子邮件，作业在发送第一封电子邮件后崩溃。

[Pipeline] End of Pipeline an exception which occurred:     in field hudson.model.Slave.launcher    in object hudson.slaves.DumbSlave@ae938e61 .... and many more

此代码的问题在于 getComputer() 部分。在管道中，您应该只使用 Serializable 而从 getComputer() 返回的 SlaveComputer 不是。

https://javadoc.jenkins.io/hudson/slaves/SlaveComputer.html

你应该做的是将这部分移动到一个用 NonCPS 注释的函数中

       @NonCPS
       def shallTrigger() {
              for (aSlave in hudson.model.Hudson.instance.slaves) {
                    def thisSlave = aSlave.name
                    echo 'Name: ' + thisSlave + ' is being checked.'
                    if ( aSlave.getComputer().isOffline().toString() == 'true') {
                        slaveState = 'OFFLINE'
                        echo 'Name: ' + thisSlave + ' is ' + slaveState + ' !'
                        emailext (
                          mimeType: 'text/html',
                          body: "${env.JOB_NAME} found an OFFLINE node: ${name}  ",
                          subject: "Jenkins ERROR: Build Node ${name} is OFFLINE " ,
                          to: 'jfisher@xxx')
                    }
              }
       }
