The maven configuration file is settings.xml, which can be found in the following paths:
------ $M2_HOME/conf/settings.xml: global settings, in the maven installation directory;
---- -- ${user.home}/.m2/settings.xml: User settings, which need to be added manually by the user. You can copy the settings.xml file in the installation directory to modify it.
The relationship between the two files is: if the two files exist at the same time, the contents of the files will be merged, and the same settings will be based on the settings.xml set by the user.
