'artifactId' is missing. @ line 2, column 109

错误背景:
本地能够正常启动和调试应用，就是打包构建失败。

详细错误信息如下:

[ERROR] [ERROR] Some problems were encountered while processing the POMs:

最关键的信息如下:

[ERROR]     'artifactId' is missing. @ line 2, column 109

错误原因:
子pom文件不经意间操作不小心去除了artifactId，导致项目构建打包时找不到对应的子模块，从而无法构建，导致报错。

解决方式:
加上即可,如下图所示:
