IntelliJ Idea14 创建Maven多模块项目

我们项目中会有很多模块，每个模块都是独立的maven project，如果项目不大，我们还可以独立的编译测试运行每个模块，但是随着项目越来越大，我们不得不想办法让我们的工作变得简单，这时就出现了Maven聚合的方式来完成编译所有模块。把多个模块或项目聚合到一起，我们可以建立一个专门负责聚合工作的project。

一：新建一个空白标准maven project（不要选择Create from archetype选项）因为该项目是作为一个Parent project存在的，可以直接删除src文件夹。Parent project用于组织不同的Module，不实现逻辑。

1、首先聚合模块必须为pom，否则无法构建，聚合模块的pom没有实质性内容，只有一个pom.xml文件。只是用来帮助其他模块构建的工具。  
2、<modules>元素，它是聚合的最核心配置。可以声明多个module元素。每个module的值都是一个当前pom的相对目录。模块所处的目录必须和<module>模块所处的目录一致。  
3、<dependencyManagement> 通过它元素来管理jar包的版本，让子项目中引用一个依赖而不用显示的列出版本号。Maven会沿着父子层次向上走，直到找到一个拥有dependencyManagement元素的项目，然后它就会使用在这个dependencyManagement元素中指定的版本号。  
4、<pluginManagement> 插件的版本管理，同<dependencyManagement>。

                </dependency>
            </dependencies>
        </dependencyManagement>
    
        <build>
            <finalName>${project.artifactId}</finalName>
            <plugins>
                
                <plugin>

                    <configuration>
                        <encoding>UTF-8</encoding>
                    </configuration>
                </plugin>
                
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-compiler-plugin</artifactId>
                    <version>3.2</version>

                </plugins>
            </pluginManagement>
        </build>
    </project>

二：创建Module，继承Parent project

<parent>
            <groupId>jstudio-freeway</groupId>
            <artifactId>org.jstudio.freeway.parent</artifactId>
            <version>1.0-SNAPSHOT</version>
        </parent>

三：在Parent Project 中添加子模块

<modules>
            <module>xxxxx1</module>
            <module>xxxxx2</module>
    </modules>
