我试图在Eclipse中的Tomcat上运行我的应用程序，但是在本地主机上启动Server Tomcat v8.5 Server无法启动。错误。
我已经尝试了一切。我什至在Ubuntu上清除了Java，在Eclipse中创建了新的工作区，即新的Tomcat服务器实例。第一次跑步时还可以。但是随后我对代码进行了一些更改，尝试运行它，再次出现此错误。
我不认为这是我的代码问题，因为发生这种情况时，我无法在服务器上运行任何应用程序。
非常感谢您的帮助，因为我已经尝试解决这一问题已有两天了。
我在带有此错误弹出窗口的窗口之前在Eclipse中获得以下输出：

我最近有同样的问题。冲突发生在pom.xml中，因为我同时包含了模仿所有和依赖核心。您必须检查您的pom.xml。
