[java] tomcat The required Server component failed to start so Tomcat is unable to start

问题出现：
Server Tomcat v8.5 Server at localhost failed to start. 或者The required Server component failed to start so Tomcat is unable to start 问题。
我是这么解决的，给大家提供一个参考：
双击Servers里面的Tomcat。
进入了Overview页面，把Publish module contexts to separate XML files选项勾上，问题解决。
