Jenkins groovy插件文件未找到异常

我有一个脚本，可以找到所有空闲的从机，并使用Jenkins系统groovy创建一个文本文件。我能够创建一个空文件，并找到所有空闲的从机，然后将其附加到我得到的文件“idle_slaves.list”中java.io.FileNotFoundExceptionexception。有人能帮我吗

import jenkins.*
import hudson.*
import jenkins.model.Jenkins

jenkins = jenkins.model.Jenkins

File file1 = new File(build.workspace.toString() + "/idle_slaves.list")

if(build.workspace.isRemote())
{
    channel = build.workspace.channel;
    fp = new FilePath(channel, build.workspace.toString() + "/idle_slaves.list")
} else {
    fp = new FilePath(new File(build.workspace.toString() + "/idle_slaves.list"))
}

if(fp != null)
{
    fp.write("", null); //writing to file
} 

for (node in Jenkins.instance.nodes) {
  computer = node.toComputer()
  if (computer.getChannel() == null) {
    continue
  }
if (computer.isIdle()) {
 slave = node.name.toString()
file1.append( slave )
}
}

实际上，文件本身尚未创建：）

如果要创建文件，只需创建一个指向路径的指针，然后添加以下行

file1.createNewFile() 

还要确保您创建的文件具有访问权限，否则您将被拒绝

添加以下代码以进行确认

// check if the file exists
        boolean exists = file.exists();
        if(exists == true)
        {
            // printing the permissions associated with the file
            println "Executable: " + file.canExecute();
            println "Readable: " + file.canRead();
            println "Writable: "+ file.canWrite();
        }
        else
        {
            println "File not found.";
        }

希望有帮助：）

为什么不使用jenkins/hudson库而不是手动阅读：

pipeline {
    agent {label 'slave'}
    stages {
        ...
    }
}

def jenkins = Jenkins.instance
def computers = jenkins.computers

computers.each{ 
  println "${it.displayName} ${it.hostName}"
}

for (aSlave in hudson.model.Hudson.instance.slaves) {

pipeline {
    agent {label 'slave'}
    stages {
        ...
    }
}

def jenkins = Jenkins.instance
def computers = jenkins.computers

computers.each{ 
  println "${it.displayName} ${it.hostName}"
}

for (aSlave in hudson.model.Hudson.instance.slaves) {

pipeline {
    agent {label 'slave'}
    stages {
        ...
    }
}

def jenkins = Jenkins.instance
def computers = jenkins.computers

computers.each{ 
  println "${it.displayName} ${it.hostName}"
}

for (aSlave in hudson.model.Hudson.instance.slaves) {

pipeline {
    agent {label 'slave'}
    stages {
        ...
    }
}

def jenkins = Jenkins.instance
def computers = jenkins.computers

computers.each{ 
  println "${it.displayName} ${it.hostName}"
}

for (aSlave in hudson.model.Hudson.instance.slaves) {

这意味着找不到该文件。或者可能无法访问。错误行？你能分享你的堆栈跟踪吗？还有你的要求是什么，也许还有其他的方法。我想找到空闲的奴隶并在每个奴隶上运行一个作业。
