我的代码是在没有其他作业正在运行或排队时运行清理作业，除了清理作业-

import hudson.model.*

def runningBuilds = []
def queuedBuilds = []

def manager = Hudson.instance

def queue = manager.queue

if (queue.items.size() > 0) {
    queuedBuilds = queue.items.collect { it.task.url }
}

for (computer in manager.computers) {
    for (executor in computer.executors) {
        if (executor.isBusy()) {
            def currentBuildUrl = executor.currentExecutable.url
            if (!currentBuildUrl.matches('.*/clean_test/\\d+/'))
                runningBuilds << currentBuildUrl
                println "excluding current job from running builds: $currentBuildUrl"
            }
        }
    }
}

def maxRetries = 70
def retryIntervalSec = 10

def retries = 0
while (retries < maxRetries) {
    if (runningBuilds.isEmpty() && queuedBuilds.isEmpty()) {
        break
    }

    if (retries == maxRetries - 1) {
        println "Max retries reached. Exiting..."
        return
    }

    println "Waiting for running and queued builds to complete..."
    sleep(retryIntervalSec * 1000)
    retries++
}

def queueAfterWait = manager.queue

if (!isAnyJobRunningOrQueued(queueAfterWait)) {
    // Your cleanup logic here
    println "Running cleanup job on master node..."
    println "List current files in /tmp folder"
    println runCommand("ls -ltrh /tmp/")
    println "-------------------------------------------------------------------------------------------------------------"

    def diskSpaceBeforeCleanup = runCommand("ls -ltrh /tmp | head -n 1")
    println "TMP folder disk space before cleanup is $diskSpaceBeforeCleanup"

    // runCommand("rm -rf /tmp/<files>")
    println "-------------------------------------------------------------------------------------------------------------"

    def diskSpaceAfterCleanup = runCommand("ls -ltrh /tmp | head -n 1")
    println "TMP folder disk space after cleanup is $diskSpaceAfterCleanup"
    println "-------------------------------------------------------------------------------------------------------------"
} else {
    println "Skipping cleanup as other Jenkins jobs are running or queued."

    println "Running builds:"
    if (runningBuilds.isEmpty()) {
        println "No running builds."
    } else {
        println runningBuilds.join('\n')
    }

    println "Queued builds:"
    if (queuedBuilds.isEmpty()) {
        println "No queued builds."
    } else {
        println queuedBuilds.join('\n')
    }
}

def runCommand(String command) {
    def process = command.execute()
    process.waitFor()
    return process.text.trim()
}

def isAnyJobRunningOrQueued(queue) {
    // Check running builds on all computers
    for (computer in manager.computers) {
        for (executor in computer.executors) {
            if (executor.isBusy()) {
                return true
            }
        }
    }

    // Check queued builds
    if (queue.items.size() > 0) {
        return true
    }

    return false
}

尝试使用Jenkins.instance而不是哈德逊，并删除了管理器以及def jenkins = Jenkins.instance

def queue = jenkins.queue

and this-
def queue = Jenkins.instance.queue

但我还是看到了错误
