Answer 1

It seems your downloaded dependencies got corrupted somehow.

Try running:

mvn -U clean install

Answer 2

I do answer beacuse I do not have enough reputation to make comment.So;

In STS I got the same error then found @dhamibirendra's answer and I tried and it worked in different way. (Right Clik On Project -->Run as Maven Build(not 3dot)) then write U- clean install on goal and run.(Do not forget to set Maven Runtime to external) After is done I got same error again on same project. Then I delete existing project and create new one and works with no problem. Maybe it helps someone.

Answer 3

右键单击Project->以Maven Build运行，然后单击build clean上的选项并一步一步安装，然后在目标部分U-clean install中运行此命令，然后单击Run。如果仍然看到，请刷新项目问题，然后删除旧项目并创建新项目。
