若依项目(ruoy-vue)多模块依赖情况简要分析

主pom文件关键点分析

• properties标签声明变量信息：版本号、编码类型、java版本
• spring-boot依赖形式：spring-boot-dependencies、pom、import
• dependencies中添加本项目内部模块，同时在modules中声明模块
• packaging打包选择pom
• 设置打包maven-compiler-plugin相关配置
• 添加阿里云仓库作为项目仓库和插件仓库

模块间依赖关系

• 每个模块在自己的pom文件中添加dependency依赖即可，不用写版本号，已经统一在主pom中管理。
• 每个模块将主pom文件的包标识作为自己的parent标签内容
• 入口包(admin)的pom文件中packaging为jar
