我正在遵循 Jenkins 文档中的“入门”指南；但是，我无法让 Jenkins 正常运行。当我运行命令时，java -jar jenkins.war --httpPort=8080我收到一系列警告/错误，Jenkins 不会按预期运行。我无法安装任何插件或完成入门指南的下一步。
我收到的第一个警告是删除临时文件。它似乎失败了，因为该位置没有文件。
Jan 27, 2018 11:58:13 PM Main deleteWinstoneTempContents
WARNING: Failed to delete the temporary Winstone file
/var/folders/mg/r5m253mx4hz75sk1f_gn5xg80000gn/T/winstone/jenkins.war
我收到的下一个警告是 Jetty 警告。我不知道这里有什么问题，因为我不熟悉 Jetty。
Jan 27, 2018 11:58:16 PM
org.eclipse.jetty.server.handler.ContextHandler setContextPath
WARNING: Empty contextPath
下一个警告是，
Jan 27, 2018 11:58:34 PM jenkins.slaves.DeprecatedAgentProtocolMonitor
initializerCheck
WARNING: This Jenkins instance uses deprecated Remoting protocols: CLI-
connect,CLI2-connect,JNLP-connect,JNLP2-connectIt may impact stability
of the instance. If newer protocol versions are supported by all system
components (agents, CLI and other clients), it is highly recommended to
disable the deprecated protocols.
最后，我得到了关于某种类型的 Hudson 或认证问题的冗长堆栈跟踪。

正如我所说，我逐字逐句地按照他们的指示进行操作，它们非常简单，但它不起作用。您可以提供的任何帮助将不胜感激。谢谢。
