add your own jar maven project

1. Place the jar into his own maven repository

1) The first step to get this into the jar maven installation directory, D: \ Program Files (x86) \ apache-maven-3.6.0

2）打开cmd，输入指令 mvn install:install-file -Dfile="D:\Program Files (x86)\apache-maven-3.6.0\test.jar"  -DgroupId=cn.ffcs -DartifactId=test  -Dversion=1.0.0 -Dpackaging=jar

(Here involving a cmd, if a directory with spaces use "" in quotes)

This will add resources in the project pom.xml file
