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
