在给jekins创建windows从节点时，发现启动方式里找不到 " Launch slave agents using Java Web Start "这个选项，百度之后，发现大家都配置了这个东西：
然而，我配置了还是没有，最后在stackoverflow上看到一个回答：
As of Jenkins version 2.176.3, there is option enabled when "Launch agent by connecting it to the master" which is same as "launch agent via java web start" once you enable the "Manage Jenkins => Configure Global Security => Agents => TCP port for inbound agents" as mentioned above. e.g. Fixed: 50000
在启用了 TCP port for inbound agents 选项后，Launch agent by connecting it to the master选项和launch agent via java web start是一样的
