springboot 出现Failed to instantiate SLF4J LoggerFactory Reported exception: java.lang.NoClassDefFound

今天建了一个springboot的项目包了很多的错，如下：

而且上面说的包也有没有缺的，然后我在网上查啊查没发现什么错误，我得天啊，浪费了好多时间，然后我根据jar包所在位置把仓库里的包全部删除，然后在pom.xml中添加如下

org.springframework.boot
spring-boot-starter-parent
2.0.0.RELEASE








org.springframework.boot
spring-boot-starter-web

然后保存就会去中央仓库下载下载完了就刷新一下就ok了
