3. Modification of settings.xml configuration file

Find the localRepository tag in the configuration file. This tag configures the location of the local warehouse. You can customize a folder to save it (try not to use Chinese). The maven project will first look for dependencies from the local warehouse. If it cannot be found , and then go to the central warehouse to download, and the downloaded dependency packages will be saved to the local warehouse.
