我有一个问题：（挂起-等待下一个可用的执行者）
控制台日志：

这看起来与Jenkins错误有关：FATAL: java.lang.Integer cannot be cast to hudson.slaves.NodeProperty .您最近是否升级了Jenkins？

转到Jenkins安装的根文件夹。
在config.xml中查找<globalNodeProperties>
如果它看起来像这样，它可能没有正确升级：

<globalNodeProperties>
  <hudson.slaves.EnvironmentVariablesNodeProperty/>
  <int>2</int>
  <string></string>
  <string></string>
  ...
</globalNodeProperties>

XML格式已更改，它应该如下所示（请注意，int不再是globalNodeProperty，也就是您得到的异常：

<globalNodeProperties>
    <hudson.slaves.EnvironmentVariablesNodeProperty>
      <envVars serialization="custom">
        <unserializable-parents/>
        <tree-map>
          <default>
            <comparator class="hudson.util.CaseInsensitiveComparator" reference="../../../../../../views/listView/jobNames/comparator"/>
          </default>
          <int>2</int>
          <string></string>
          <string></string>
          ...
        </tree-map>
      </envVars>
    </hudson.slaves.EnvironmentVariablesNodeProperty>
  </globalNodeProperties>

我最后通过删除ruby-runtime插件解决了这个问题。
进入JENKINS_HOME/插件和sudo rm -rf ruby-runtime*
