Central warehouse setup

By default, Maven downloads required JAR packages from foreign servers. However, downloading from foreign servers is time-consuming and requires high network requirements in China. The best way is to change the address of the central warehouse to the domestic warehouse provided by Ali Cloud. Ali Cloud warehouse is free and the best warehouse in China. Add the following code to your Maven configuration. Maven only wakes up and downloads from foreign servers when the required package cannot be downloaded from Ali’s cloud repository.

How to know the groupId and artifactId of the required package?
