1.项目父模块pom.xml

1.packaging 为pom
2.可以继承其他pom，如项目用了spring-boot-starter-parent
3.modules下定义子模块的artifactId标识

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <packaging>pom</packaging>
    <modules>
        <module>HaoohoCommon</module>
        <module>HaoohoTasks</module>
        <module>HaoohoDataCenterApp</module>
    </modules>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.5.2</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <groupId>org.haooho</groupId>
    <artifactId>datacenter</artifactId>
    <version>1.0-dev</version>

1.子模块HaoohoCommon pom.xml

1.common 是其他模块依赖
2.packaging 为jar
3.spring-boot-maven-plugin插件，创建spring可依赖的jar包
