我似乎无法让我的服务器开始运行。不知道这是否相关，但使用联想瑜伽2。尝试了一些建议的解决方案，但似乎都没有。任何帮助将不胜感激！

Answer 1

首先检查另一个应用程序是否正在使用tomcat端口，tomcat上的默认端口是8080

netstat -an | find ":8080"

还要检查web.xml中的依赖项。这个错误也可能是因为你需要升级它们，我有一个类似的问题，这解决了将icu4j更新到最新版本，这个帖子也可能有帮助 http://maven.40175.n5.nabble.com/Problem-when-mvn-site-site-Generating-quot-Dependencies-quot-report-td113470.html

希望它有所帮助！
