启动Jenkins服务时的Java异常"java.lang.IllegalArgumentException: Expecting前缀“

Question

我正在将Jenkins服务器升级到2.357，并将Java从1.8升级到11，以支持它。

然而，当我启动Jenkins时，它失败了，journalctl -xe给出了下面的错误

看起来它指向了异常，Exception in thread "main" java.lang.IllegalArgumentException: Expecting ----prefix=VALUE but found no value，但我似乎无法理解它。如果能提供帮助，我们将不胜感激！

Java版本：

此错误指示您正在以无效值传递--prefix启动参数。只有当您有Jenkins的自定义上下文路径时，才需要--prefix。

如果将Jenkins服务器作为服务启动，请检查服务定义，并确保只传递所需的参数。服务定义位于/etc/systemd/system/jenkins.service
