新建目录my-lib,将jar包移动到目录中，添加pom文件（用alipay测试）

<project xmlns="http://maven.apache.org/POM/4.0.0"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

http://maven.apache.org/xsd/maven-4.0.0.xsd">

<modelVersion>4.0.0</modelVersion>

<groupId>org.alipay</groupId>

<artifactId>alipay-resource</artifactId>

<version>1.0.0</version>

<name>alipay</name>

<description>alipay jar lib</description>

</project>

cmd进入该目录下，执行命令

mvn install:install-file -Dfile=alipay-sdk-java20171201160035-source.jar -DgroupId=org.alipay -DartifactId=alipay-resource -Dversion=1.0.0 -Dpackaging=jar
