Lunux Ubuntu Jenkins 构建节点上又出现“无法生成助手”错误？

我读过Java，自从在 linux 上迁移到 Java 14 以来无法执行生成帮助程序错误和无法执行生成帮助程序，他们的解决方案讨论了：

  • 设置
    -Djdk.lang.Process.launchMechanism=vfork
    并重新启动 
    jenkins.service
  • 停止 Gradle 守护进程
  • 添加可执行权限
    /usr/lib/jvm/java-17-openjdk-amd64/lib/jspawnhelper

就我而言，这是在运行 JDK17 的 Linux Ubuntu 构建节点上随机发生的，并且上述解决方案（以及帖子中提到的其他解决方案）均不适用。我们的构建节点不运行 

jenkins.service
（我们在 
master
节点中将 Jenkins 作为 Docker 容器运行），因此无需设置和重新启动，并且问题发生在非 摇篮步骤。 
/usr/lib/jvm/java-17-openjdk-amd64/lib/jspawnhelper
具有可执行权限。这是堆栈跟踪的示例

上面的错误显示 

nohup
无法生成（我们运行 
sh "..."
命令，它生成 
nohup
），但我看到它与 
docker ...
和 
git ...
命令类似地失败。

我有什么想法可以调试并可能解决我的情况吗？谢谢！

您修复了这个错误吗？ 我有同样的问题，在管理员修补 jenkins 代理后， git ls-remote 不起作用；无法返回

Cannot run program "nohup" (in directory "/mnt/jenkins/workspace/servicedir"): error=0, Failed to exec spawn helper: pid: 1224365, exit value: 1

以前它在不同的命令上失败并多次重新启动代理已修复，而不是在这里失败。 另外，在这个阶段，我放置了调试步骤“which nohup”，就像这样，它失败并出现相同的错误，无法运行 nogup。
