IntelliJ IDEA打开多个Maven的module且相互调用代码的方法
###1、需求
1、IntelliJ IDEA打开多个项目
2、每个同学开发一个项目，相互之前独立不影响
3、通过一个入口可以调用所有项目类、方法、属性，达到同时开发且检测代码
4、dependency只需要写一份，其余项目不用写，便可全部依赖
###2、注意事项（非常重要）
6个坑：
1、<groupId>com.yh.bi</groupId>
项目中所有的groupId要一样
2、避免循环依赖，导致程序报错
3、<scope>provided</scope>
打包的服务器运行时候需要provided，本机调试的时候，需要注释
在一个maven项目中，如果存在编译需要而发布不需要的jar包，可以用scope标签，值设为provided
4、项目、module建好之后需要添加Scala的框架支持
5、在yhProject中，可以统一对所有的module进行清理、编译、打包
6、要运行依赖中的module，则必须要将module中的Jar包，打到maven中，需要使用install
下面，是我将所有module中的Jar打到Maven中的路径：
###3、建立Project和建立module
1、只需要建立一个项目，其他项目由module建立，所有module且放在项目中。
2、本文项目为yhproject，其余都为module，分别是：mainEntrance、yhutils、yhapp、yhweb、yhgame
项目建立步鄹：
Module建立步鄹：
项目、所有module、部分module代码展示：
###4、项目之前的依赖关系
###5、代码展示
