做项目的还是 会发现 很多sdk没有maven版本的，这个时候只能手动引入jar包
以引入亚马逊支付的sdk为例
<dependency>
<groupId>org.amzon-pay</groupId>
<artifactId>amazon-pay-3.6.3.jar</artifactId>
<version>1.0</version>
<scope>system</scope>
//jar包路径相对路径
<systemPath>${project.basedir}/src/main/resources/jar/amazon-pay-3.6.3.jar</systemPath>
</dependency>
这个引入后可以发现，项目里可以找到sdk里面的方法了，本地运行项目可以发现可以正常启动，
但是使用打包后在服务器上运行会发现报错了

排查后发现 ，是由于打包的时候 没有把我们自己引入的jar 打包进项目
给spring-boot的打包插件设置一下includeSystemScope参数即可
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
//加入这个includeSystemScope
<configuration>
<includeSystemScope>true</includeSystemScope>
</configuration>
</plugin>
</plugins>
</build>
在运行 可以发现 项目可以正常跑起来了
