尝试使用Jenkins.instance而不是hudson并删除manager
def jenkins = Jenkins.instance
def queue = jenkins.queue
和这个
def queue = Jenkins.instance.queue
但我仍然看到错误

Tried using Jenkins.instance instead of hudson and removed manager as well
def jenkins = Jenkins.instance
def queue = jenkins.queue
and this-
def queue = Jenkins.instance.queue
But I still see errors

# 答案1
**得分**: 1
这段代码的一部分看起来有问题：
```groovy
def isAnyJobRunningOrQueued(queue) {
// 检查所有计算机上运行的构建
for (computer in manager.computers) {
你在方法中使用了脚本变量 manager，但没有将其作为参数传递。你可以尝试将其改成如下所示：
def isAnyJobRunningOrQueued(queue, manager) {
// 检查所有计算机上运行的构建
for (computer in manager.computers) {
并且修改 isAnyJobRunningOrQueued 方法的调用：
if (!isAnyJobRunningOrQueued(queueAfterWait, manager)) {
希望这对你有所帮助。
更新：
另一种选项是将 manager 声明为全局变量，而不是 def manager = bla-bla。以下是一个小的测试脚本，以便你了解 Groovy 中局部变量和全局变量的工作方式：
def scriptVar = '我是局部变量'
globalVar = '我是全局变量！'
someMethod()
def someMethod() {
// println "scriptVar = $scriptVar" -- 这将失败！！！
println "globalVar = $globalVar"
}
英文:
To me this part of code looks suspicious:
def isAnyJobRunningOrQueued(queue) {
// Check running builds on all computers
for (computer in manager.computers) {
----------
You're using script variable manager in the method without passing it as a parameter. Could you try to change it to:
def isAnyJobRunningOrQueued(queue, manager) {
// Check running builds on all computers
for (computer in manager.computers) {
----------
and change the call of the isAnyJobRunningOrQueued method:
if (!isAnyJobRunningOrQueued(queueAfterWait, manager)) {
-------
I hope it will help.
Update:
Another option is to declare manager as a global variable manager = bla-bla instead of def manager = bla-bla. Here is the small test script so you get the idea how local and global variables work in Groovy:
def scriptVar = 'I am local'
globalVar = "I'm global!"
someMethod()
def someMethod() {
// println "scriptVar = $scriptVar" -- it fails!!!
println "globalVar = $globalVar"
}
