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：

<dependency>

<groupId>mysql</groupId>

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

</dependency>

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

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