springboot集成java+groovy+lombok混合编程使用maven多模块打包实例

springboot多模块打包实例

由于在项目中引入了groovy编程，并且使用了lombok，在运行时没发现什么问题，但是最后打包部署时出现一系列问题。查了许久资料终于解决，特将解决方案写成文档记录一下

项目结构

upms-integrate      父模块
├─upms-base         公共模块
│
├─upms-web          管理后台-web
│
├─upms-generator    代码生成器

upms-admin模块依赖upms-base模块

maven打包各模块配置

• upms-integrate父模块

各模块按以上配置后，即可使用mvn clean install/package 指令打包了。
也可以使用-pl upms-web指定打包模块，前提是要先把该模块依赖的所有子模块安装到本地或远程仓库

(重点)springboot在混合java+groovy编程并且使用lombok的情况下打包配置

java混合groovy打包需要使用groovy-eclipse-compiler插件，并且在引入了lombok的情况下又会有一些问题。
解决方法为：上述各模块配置不变，在父模块中增加以下配置

以上问题得到解决

maven打包异常

• 无法解析lombok的@Data的注解。Groovy:unable to resolve class Delegate , unable to find class for annotation
  需要使用groovy-eclipse-compiler插件打包
• The import XXX cannot be resolved
  被依赖的子模块使用了spring-boot-maven-plugin打包插件，导致引用模块无法发现公用模块的包文件
