创建maven项目后缺少jar包下载失败等问题

transfer.......fail.........等问题

The container 'Maven Dependencies' references non existing library 'C:\Users\yst\.m2\repository\net\bytebuddy\byte-buddy\1.9.12\byte-buddy-1.9.12.jar'

The project cannot be built until build path errors are resolved等

 

选中项目，右键选择maven——update project 勾选Force Update of Snapshots/Releases，OK
