聚合模块为项目目录的最顶层,其他模块作为聚合模块子目录而存在。目的是为一次构建多个项目模块。
我自己化了一个关于项目的关系:
maven-aggregate作为maven pom项目,需要定义pom.xml的 packaging 为 pom类型
我们还是参照 maven的依赖特性,冲突解决(五) 创建 maven-01 maven-02 maven-03工程,通过maven-aggregate pom工程 对这三个maven项目做一个聚合,配置如下:

<!-- 子模块 指定项目pom的位置 ..代表上一级目录-->
<modules>
<module>../maven-01</module>
<module>../maven-02</module>
<module>..maven-03</module>
</modules>
</project>
对 maven-aggregate执行下mvn clean compile

这样我们就完成 maven对子模块的聚合 ,像我们平常用的dubbo jetty tomcat spring hibernate等等 都是按模块 去开发,一次编译 各个模块都能紧密联系在一起了。我们在平常开发项目也需要适当的去分模块开发,
这是dubbo的子模块,分了很多子模块:下载
pom继承是为了抽出重复配置,通常配置在父模块中,为子模块提供使用,这样可以做到“一处声明,处处使用”。
1.常用的pom被继承的元素
Xml代码 下载
groupId :项目组 ID ,项目坐标的核心元素;
version :项目版本,项目坐标的核心元素;
description :项目的描述信息;
properties :自定义的 Maven 属性;
dependencies :项目的依赖配置;
dependencyManagement :醒目的依赖管理配置;
repositories :项目的仓库配置;
build :包括项目的源码目录配置、输出目录配置、插件配置、插件管理配置等;
1.配置maven-aggregate pom文件:
Xml代码 下载
<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>
<groupId>com.sohu.train</groupId>
<artifactId>maven-aggregate</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>pom</packaging>
<!-- 子模块 -->
<modules>
<module>../maven-01</module>
<module>../maven-02</module>
<module>../maven-03</module>
</modules>
<!-- 统一配置构件的版本号 -->
<properties>
<junit.version>3.8.1</junit.version>
</properties>
<!-- 依赖管理 -->
<dependencyManagement>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>${junit.version}</version>
<scope>test</scope>
</dependency>
</dependencies>
</dependencyManagement>
</project>
maven-01,maven-02,maven-03 需要配置parent ,dependencies,同时对junit做一个依赖,3个工程的pom配置如下:
Xml代码 下载
<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>
<!-- 指定父pom的坐标及pom位置 -->
<parent>
<groupId>com.sohu.train</groupId>
<artifactId>maven-aggregate</artifactId>
<version>0.0.1-SNAPSHOT</version>
<relativePath>../maven-aggregate/pom.xml</relativePath>
</parent>
<artifactId>maven-03</artifactId>
<packaging>jar</packaging>
<!-- 添加对junit依赖,这样公用配置只需要在maven-aggregate中去配置 -->
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
</dependency>
</dependencies>
</project>
这样就完成pom的继承,讲公用的jar一次配置,就可以实现多处引用了。
