报错：程序包XXX不存在
==============================================================================
OK，开始研究这个问题：
1.服务开始打包啦，先使用clean进行清理
一般清理都会成功，就是删除target目录下的编译的class文件以及配置等
2.开始使用install进行打包的操作
开始打包，控制台显示日志：
但是 报错来的也很突然：
也就是说，明明程序包是存在的，但是依旧报错：

那么这个问题怎么解决呢？
3.解决方法
最快捷简单的办法，就是将父级项目的pom.xml文件中，的maven插件注释，【只保留子模块的插件即可】【我这里子级模块中都没有显示加入插件，所以只注释了父级项目中的maven插件，就可以打包成功了】即可
<build>
<!--<plugins>-->
<!--<plugin>-->
<!--<groupId>org.springframework.boot</groupId>-->
<!--<artifactId>spring-boot-maven-plugin</artifactId>-->
<!--</plugin>-->
<!--</plugins>-->
</build>
然后再进行打包操作，即可成功：
