IDEA 项目运行报错 Error starting Tomcat context. Exception:

IDEA 版本 2021.3.2 maven 版本 3.5.0
2月15号遇到这个问题
16号把IDEA 完全卸载重装了一遍好了
晚上再次出现这个问题
目前仍在寻找解决办法
如成功会再更新

点开IDEA 右侧maven 发现依赖报错
公司里的一个大佬说可能因为IDEA版本太高而Maven 版本较低引起
准备去试试看
2.17 -11：45
一上午了 从2021.3.2一路卸载重装到2020.3.4 还是没有恢复正常
我好菜
fuck IDEA
fuck Maven

2.17.15.45
对了 上午还有这个数据库驱动的问题
解决后仍然是最上面图的问题
下午公司的技术经理来了 找半天也没解决
他走了之后我重新导了下这个
解决之后项目可以跑起来了
呜呜 老丢人了
