使用有效的 Jenkins 脚本"No such static method found: staticMethod"失败的管道

Question

我正在尝试实现用于监视从属代理的jenkins脚本在这篇文章之后：；https://www.jenkins.io/doc/book/managing/nodes/"我在jenkins脚本consul中成功地运行了这个脚本，但当我在管道中运行它时，我一直失败

import hudson.node_monitors.*
import hudson.slaves.*
import java.*
import javax.activation.*
import thread.*
import java.lang.*

def getEnviron(computer) {
def env
def thread = Thread.start("Getting env from ${computer.name}", { env = computer.environment })
thread.join(2000)
if (thread.isAlive()) thread.interrupt()
env
}
def slaveAccessible(computer) {
getEnviron(computer)?.get('PATH') != null
}

def numberOfflineNodes = 0
def numberNodes = 0
pipeline {
parameters {
string(name: 'Slack_channel',
description: 'OTT DevOps channel',
defaultValue: '#ott-devops-team')
}
environment {
// Slack configuration
SLACK_COLOR_DANGER  = '#E01563'
SLACK_COLOR_INFO    = '#6ECADC'
SLACK_COLOR_UNSTABLE    = '#E01563'
SLACK_COLOR_WARNING = '#FFC300'
SLACK_COLOR_GOOD    = '#3EB991'
}

agent {label "master"}
stages {
stage('monitor and restart slave agents') {
steps {
script {

def jenkins = Hudson.instance
for (slave in jenkins.slaves) {
def computer = slave.computer
numberNodes ++
println ""
println "Checking computer ${computer.name}:"
def isOK = (slaveAccessible(computer) && !computer.offline)
if (isOK) {
println "ttOK, got PATH back from slave ${computer.name}."
println('tcomputer.isOffline: ' + slave.getComputer().isOffline());
println('tcomputer.isTemporarilyOffline: ' + slave.getComputer().isTemporarilyOffline());
println('tcomputer.getOfflineCause: ' + slave.getComputer().getOfflineCause());
println('tcomputer.offline: ' + computer.offline);

} else {
numberOfflineNodes ++

if (!slave.getComputer().getOfflineCause().toString().contains("Disconnected by")) {
computer.setTemporarilyOffline(false, slave.getComputer().getOfflineCause())
}
} else {
computer.connect(true)
}
}
}
println ("Number of Offline Nodes: " + numberOfflineNodes)
println ("Number of Nodes: " + numberNodes)
}
}
}
}
post {

错误代码为：

在http://jenkins_home/script工作正常/scriptApproval/中没有等待的审批请求

Answer 1

异常来自脚本安全插件。

您将在Manage Jenkins下看到->在脚本审批过程中(或浏览到<your-jenkins-host>/scriptApproval(，您需要审批才能运行脚本的行。

如果有多条违规线路，则需要重复此过程，直到满足所有安全要求。

另一种方法是完全禁用管道中的groovy沙盒(当您配置管道时，就在脚本框下(，但除非您正在测试，否则最好将其勾选。
