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：

 

 

 

4.同时需要注意，子模块的pom.xml文件中需要指定插件
