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

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

Reason for error: Maven cannot find mysql

Solution: Due to IDEA dependency mysql before:

<dependency>

<groupId>mysql</groupId>

<artifactId>mysql-connector-java</artifactId>

</dependency>

Modification: Specify your mysql version in the pom.xml file . Note: The mysql version here should be consistent with the local mysql version

<dependency>
   <groupId>mysql</groupId>
   <artifactId>mysql-connector-java</artifactId>
   <version>8.0.21</version>
   <scope>runtime</scope>
</dependency>
