为什么我的POM.XML里面在添加mysql java connector的时候报错？

[adiosnino]

<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.30</version>
</dependency>

[adiosnino]

ArtifactTransferException: Failure to transfer mysql:mysql-connector-java:jar:5.1.30 from http://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact mysql:mysql-connector-java:jar:5.1.30 from/to central (http://repo.maven.apache.org/maven2): No response received after 60000
