IDEA 多模块项目启动编译整个project

**问题描述：**

> maven架构的Java项目构建了多个module，然后module A依赖module B。由于maven A依赖的是module B 的jar，所以当module B 源码更新之后存在module A不能及时更新最新版module B的jar包的问题

**解决思路：**

> maven整个生命周期的作用域都是针对自身pom所在的module，无法更新pom中的某个jar，所以只能依靠其它方式实现。这时想到当持续集成时可以通过设置多个打包步骤，先打包module B，然后打包module A，这样就能保证module A使用的B的jar包一直是最新的。同理，本地开发环境可以通过设置IDEA Run Configurations中的Before Launch来控制启动类执行前的操作，在这里先编译B，再编译A，可以使得每次运行的A都依赖了最新版的B。

# 一、项目结构 #

cbam-mobile
    ├── cbam-mobile-service -- 业务模块
    └── cbam-mobile-web -- web模块

# 二、项目pom文件 #

**cbam-mobile**

**cbam-mobile-service**

**cbam-mobile-web**

# 三、IDEA配置 #

如下图，这里我配置了父project cbam-mobile 的install，这样就能保证每次cbam-mobile-web启动时能依赖到最新的cbam-mobile-service
