Turn it off and use the maven command line to operate maven. Do not use it directly in the IDE

It’s a common problem in eclipse, but it’s not found in idea! You can also download the jar package to the local warehouse, and then specify your local warehouse

Find settings.xml and add the following code to the mirrors tag

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

This situation is usually because some files cannot be found, the download times out, etc.
