java - 本地主机上的服务器 Tomcat v8.5 服务器无法在 Eclipse 中启动

Question

我正尝试在 Eclipse 中的 Tomcat 上运行我的应用程序，但出现Server Tomcat v8.5 Server at localhost failed to start. 错误。我已经尝试了一切。我什至在 Ubuntu 上清除了 java，在 Eclipse 中创建了一个新的工作区，新的 Tomcat 服务器实例。我第一次运行时还可以。但是后来我对代码做了一些更改，尝试运行它，但我又遇到了这个错误。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我的任何应用程序。非常感谢您的帮助，因为我已经尝试解决这个问题两天了。

我在 Eclipse 中的这个错误弹出窗口之前得到了这个输出:

我最近遇到了同样的问题。冲突在 pom.xml 中，因为我同时包含 mockito-all 和 mockito-core 依赖项。你必须检查你的 pom.xml。
