项目运行出错Cannot instantiate interface org.springframework.boot.SpringApplicationRunListener

Question

前几天改了另一个java项目的spring相关的设置，结果导致所有项目运行都出错了，怀疑是jar之间有冲突或者缺失。
用maven helper 检查没有发现jar包冲突。搞了2天，还是解决不了，麻烦各位帮忙看看是什么问题。
项目运行报错如下。

很奇怪的写法，一般start依赖不需要你指定version，

https://start.aliyun.com/

阿里的脚手架，你选择你要的依赖和boot版本，然后把pom.xml下载下来，然后把你的额外的依赖加进来，基本就不会出现这种版本冲突的问题了
