ne-parent是父模組

ne-commo是公共元件模組

ne-web是專案入口模組

錯誤：

ne-web模組打包的時候，找不到ne-commo公共元件模組的包，找不到ne-commo公共元件模組的類，

原因：

1、ne-commo不能新增spring-boot-maven-plugin外掛，如果添加了spring-boot-maven-plugin，當執行maven的package打包命令時，這個SpringBoot外掛會在Maven的package後進行二次打包，目的為了生成可執行jar包；

2、二次打包後其他模組引用ne-commo模組就會報錯找不到xxx包，找不到xxx類錯誤

ne-commo子模組的pom.xml中build內容如下：

    <modelVersion>4.0.0</modelVersion>
    <groupId>com.upincar.ne.commo</groupId>
    <artifactId>ne-commo</artifactId>

注：進行如上配置之後，要釋出的子模組打war包時，先打包公共模組，再打包要釋出的子模組，打包要釋出的子模組時就不會報找不到xxx包，找不到xxx類的錯誤了
