IDEA报错：Could not find artifact mysql:mysql-connector-java:pom:unknown in central (https://repo.maven

IDEA 运行报错：Could not find artifact mysql:mysql-connector-java:pom:unknown in central (https://repo.maven.apache.org/maven2)

报错原因：Maven 找不到mysql

解决方案：由于之前IDEA dependency mysql：

mysql

mysql-connector-java

修改：在pom.xml文件中指定你的mysql版本。注意：这里mysql 的version要和本地mysql 版本一致

   mysql
   mysql-connector-java
   8.0.21
   runtime
