Answer 1

Solution 1: Try mvn clean install in console.

Solution 2: It might happen because of the firewall on your computer. Turn off the firewall and try it again. 

Solution 3: Check if your pom.xml has similar dependency.

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>8.0.12</version>
</dependency>

Answer 2

If you are using intelliJ idea there is also an other option:

In the Maven tool window, click The Toggle Offline Mode button.

This will append the --offline option to all Maven commands that IntelliJ IDEA runs. It will also report any items that cannot be found in the local repository.

Or in Maven settings.xml:

<offline>false</offline>
