  • maven管理多模块系统

     

    1.创建mydemo项目
    cd d:mywork
    mvn archetype:create -DgroupId=com.example.mydemo -DartifactId=mydemo

    生成mydemo目录,删除该目录下src目录,修改pom.xml,将packaging值修改为:
    <packaging>pom</packaging>

    2. 然后分别创建mydemo-core、mydemo-web两个模块
    cd mydemo
    mvn archetype:create -DgroupId=www.example.mydemo.core -DartifactId=mydemo-core
    mvn archetype:create -DgroupId=www.example.mydemo.web -DartifactId=mydemo-web -DarchetypeArtifactId=maven-archetype-webapp

    3. 修改d:myworkpom.xml文件,添加
    <modules>
     <module>mydemo-core</module>
     <module>mydemo-web</module>
    </modules>

    4. 分别在mydemo-core和mydemo-web目录下的pom.xml文件中添加:

    <parent>
     <groupId>cn.webwork.mydemo</groupId>
     <artifactId>mydemo</artifactId>
     <version>1.0-SNAPSHOT</version>
    </parent>

    5. 然后在d:myworkmydemo-webpom.xml中添加依赖 mydemo-core包的信息,如下:

    <dependency>
      <groupId>cn.webwork.mydemo.core</groupId>
      <artifactId>mydemo-core</artifactId>
      <version>1.0-SNAPSHOT</version>
    </dependency>

    关于pom.xml配置文件的详细情况,请参考:
    Project Setting:http://maven.apache.org/maven-model/maven.html
    Introduction to POM:http://maven.apache.org/guides/introduction/introduction-to-the-pom.html

    6. 创建完成后,就会分别生成两个目录,然后分别对其生成相应的eclipse工程文件,方法为:
    cd mydemo-core
    mvn eclipse:eclipse

    cd ..
    cd mydemo-web
    mvn eclipse:eclipse -DdownloadSource=true -Dwtpversion=1.0 (指定wtpversion属性,用于生成wtp的工程文件)

    创建完成这两个eclipse工程文件后,就可以在eclipse中打开了。

    7. 回到 d:mywork目录下,执行mvn compile 就可以对这两个文件进行编译,还有mvn install ,mvn package等命令。

    mydemo文件下载:
    http://project.livedoor.cn/~roger/mydemo.zip

    关于mvn命令:
    在上面的过程中,大家看到诸如 mvn archetype:create / mvn eclipse:eclipse等这些命令,如何查询这些命令更多帮助信息?
    请参考:http://maven.apache.org/plugins/index.html
    其实象archetype:create eclipse:eclipse等都是maven的插件,默认安装的时候,这些插件都已经安装,还有很多第三方的插件,
    具体使用方式,都可以从上面的地址中查到。

    如,site插件, Generate a site for the current project 
    当你执行mvn site的时候,就会自动生成一个web site,用于展示你的项目信息。
