解决idea使用maven打包时无法将本地lib库文件和resource目录中的资源文件打包进jar文件的问题！！！

一、问题复现

1）项目结构如下

我们看到项目中手动添加了本地lib资源，同时bootspring的配置文件和mapper文件也放在了resouces目录中。

2）上述结构的项目在使用maven打包时，最终生成的jar文件中将不包含lib库文件，甚至有时resouces目录中的资源文件也会缺失。

生成的jar包如下（缺失了lib和resources资源文件）：

上述jar包在运行启动时会报错：

二、解决办法

在项目的pom.xml文件中添加编译选项，显示指定打包时需要包含的目录。
