According to the error message in the red box, I can't connect to Google's services, why can't I connect to Google's services? But I didn't take the initiative to connect to Google's services.

Some of the mirrors that our project relies on are foreign. For example, some frameworks are open sourced by Google, so foreign mirrors sometimes have different networks.

So, how do we solve this problem?

3. Solve the problem

I provide the following two solutions to solve the current error.

3.1 Solution 1

Use ideathe one that comes with the editor maven.

We use CTRL + ALT + Sthe shortcut key to open the setting panel ( Settings), Settingsfind it in the setting panel ( ) Build, Execution, Deployment -> Build Tools -> Maven, and Maven home directorymodify it to the system's own, as shown in the following figure:

Click OKto resolve the error.

If your CTRL + ALT + Sshortcut keys conflict, you can use the following method to open the settings panel ( Settings):

3.2 Solution 2

Instead of using ideathe built-in one maven, we still use our own installation maven.

1. First open maventhe configuration file ( settings.xml)

If you Mavendon't have it Open 'settings.xml', you can find it in the files mavenin your installation directory conf.

For example, in my maveninstallation directory D:\software\apache-maven-3.8.1, then I will confsearch for the files in the directory, that is D:\software\apache-maven-3.8.1\conf, as shown in the following figure:

2. Then in settings.xmlthe file, change the mirror address to the Alibaba Cloud mirror address.

<mirror>
    <id>alimaven</id>
    <name>aliyun maven</name>
    <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
    <mirrorOf>central</mirrorOf>
</mirror>

3. Finally, reimport the package
