I am using local maven repository and using {hinernate.version}, in my repository I could see hibernate 5, 4 both versions available. if I try to give manual version number in pom.xml throwing missing artifact - hibernate - core. jar — Ram Chowdary

I got solution for this problem I have tried many options changed hibernate version, spring version tried every possible option to fix this. after hours of struggle finally I found that it is due to mySQL connector version changed from 5.1.** to 8.0.11. it is working fine. even though in official they mentioned below values, they are not working.

Connector/J version Driver Type JDBC version MySQL Server version Status 5.1 4 3.0, 4.0, 4.1, 4.2 5.5, 5.6*, 5.7*, 8.0* Recommended version 8.0 4 4.2 5.5, 5.6, 5.7, 8.0 Development Milestone
