a. I tried to go to the local maven warehouse to delete the folder where the corresponding jar package is located, but to no avail,
b.CSDN tried to search for maven to be popular, and mybatis-plus relied on the answer to the Internet problem. Delete the library and re-download; the download is incomplete, re-download; the existence of lastupdate that is halfway stopped and then continues will cause Conflict, under again.
But none of them solved the actual problem
c. Have tried invalidate Caches / Restart, but it is also invalid
d. But in the case of keeping the red hot, the running test program passed (not passed at the beginning)
e. After commenting out the dependency of mybatis-plus, refresh maven, and then let go of the comment, the explosion disappears
