Jenkins windows node 上无法执行 system groovy script

想在jenkins windows 节点执行 Jenkins master 环境下的 groovy脚本:

jenkins version : Jenkins 2.289.1

import hudson.FilePath
import jenkins.model.*

node_workpace=build.moduleRoot.toString()

node_channel=build.workspace.channel

try{
    def cppatchfile = new FilePath(node_channel, node_workpace+"/pr_descriptions.txt")
    aString = cppatchfile.readToString()
}catch(java.nio.file.NoSuchFileException e){
    println("cppatchset.txt do not exist,build stop.")
    build.doStop()
}

String hString = null

StringBuffer sBuffer  = new StringBuffer();
for(String itemString : aString.split("
")) {
   String pr_number = itemString.split(" ")[1];
   String repo_name = itemString.split(" ")[0];
   String urlString = String.format("https://bitbucket.harman.com/projects/DM/repos/%s/pull-requests/%s/overview", repo_name,pr_number);
   String htmlString = String.format("<a href=%s>%s</a> ", urlString,pr_number.toString());
   println "url: "+urlString
   println "item: "+itemString.toString()
   sBuffer.append(htmlString);
   hString= sBuffer.toString();
}

build.description=hString// Set child build description

　　

结果发现build step 里面没有这个步骤. 可是在另一个JOB 里面是有这个步骤的.

最终发现，当JOB执行节点 是 windows节点的时候就没有这个step, 但是当执行节点是linux节点的时候可以看到这个step.

我先将节点选为 linux，进行配置后，改回节点为windows. 执行成功.
