Packaging with maven's build always fails, and there is no prompt saying which JAR package cannot be found. It just warns in the background that there is an outdated class, which may be deleted in the future. I think it is a warning, not an ERROR, so I don't care and try to package it. , query dependencies, try various guesses for 1 hour
Finally, I can't find any other reasons. Just remove the warning, replace the code that generates the warning, and pack the package that doesn't report hope. It's a success! ! !
