IntelliJ IDEA打开多个Maven的module且相互调用代码的方法

作者：silentwolfyh

这篇文章主要介绍了IntelliJ IDEA打开多个Maven的module且相互调用代码的方法，小编觉得挺不错的，现在分享给大家，也给大家做个参考。一起跟随小编过来看看吧

###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：

###7、运行结果展示

注意：我在mainEntrance执行DAG中的main文件，可以调用且执行了yhutils、yhapp、yhweb、yhgame中的代码

###8、如果建立Java 的module

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持脚本之家。
