② Find locally installed maven

Enter cmd into the bin directory at the location of the command line and enter the following command, hit Enter to start execution:

mvn install:install-file -Dfile=C:\Users\zhangsf\Desktop\ipdatabase.jar -DgroupId=zhang.jar -DartifactId=ipdatabase -Dversion=1.0 -Dpackaging=jar
