Maven问题-Unable to find main clas

同一问题的原因可能存在多种，这里的方式仅供参考

1、使用jenkins打包基于springboot的多web模块项目时出现Unable to find main class

解决方式
在项目的根目录下直接使用maven命令执行构建打包（开发环境和测试环境），发现有这个差异：

[WARNING] The POM for xxx.xxx.xxx:arcface:jar:1.0.0 is invalid, transitive dependencies (if any) will not be available, enable debug logging for more details

开发环境一直以来都打包正常，对比发现没有如上信息，抱着试一试的心态，在测试环境的仓库中把对应的jar信息删除后重新执行构建打包，最终打包成功。
