1、新建父專案modules-container，選擇maven project，作為所有子模組的容器

2、新建子專案modules-demo01，選擇maven module，module name為子模組名，parent project選擇父專案modules-container

3、建立成功之後，父專案自動對子專案進行聚合

  <groupId>com.maven.demo</groupId>
  <artifactId>modules-container</artifactId>
  <version>
 
0.0.1-SNAPSHOT</version>
  <!-- mavan模組化開發，父專案更改packaging為pom -->
  <packaging>pom</packaging>

  <name>modules-container</name>
  <url>http://maven.apache.org</url>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding
 
>
  </properties>

  <!-- 使用 dependencyManagement對所有依賴進行管理，以便子專案繼承使用-->
  <dependencyManagement>
    <dependencies>
        <dependency>
          <groupId>junit</groupId>
          <artifactId>junit</artifactId>
          <version>3.8.1</version
 
>
          <scope>test</scope>
        </dependency>
    </dependencies>
  </dependencyManagement>

  <!-- 自動聚合子模組專案 -->
  <modules>
    <module>modules-demo01</module>
    <module>modules-demo02</module>
  </modules>

4、子專案自動繼承父專案，修改pom.xml將公共groupId和version去掉

  <!-- 自動繼承父專案 -->
  <parent>
    <groupId>com.maven.demo</groupId>
    <artifactId>modules-container</artifactId>
    <version>0.0.1-SNAPSHOT</version>
  </parent>

  <!-- 去掉groupId、version，繼承使用父專案的 -->
  <!-- 
  <groupId>com.maven.demo</groupId>
  <version>0.0.1-SNAPSHOT</version>
   -->
  <artifactId>modules-demo01</artifactId>
  <name>modules-demo01</name>
  <url>http://maven.apache.org</url>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>

  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <!-- 使用父專案dependencyManagement管理的版本
      <version>3.8.1</version>
       -->
      <scope>test</scope>
    </dependency>
  </dependencies>

5、按照modules-demo01建立子專案modules-demo02，最終的目錄結構如圖：



補充：建立module子專案過程，eclipse可能丟擲如圖異常：

details資訊為：
Unable to create project from archetype [org.apache.maven.archetypes:maven-archetype-quickstart:RELEASE]
Unable to read parent POM

解決的辦法：將父專案pom.xml中所有中文刪除，包括註釋，所有子專案建立完畢後，需要的話再加回來。

6、然後對父專案進行編譯、測試、打包、安裝操作，實現對所有聚合子專案的共同操作
