Maven的多模块(Multi-Module)工程的pom编写
对于使用maven的骨架创建工程,想必大家都已经熟悉了,这里是一些常用的工程类型,如想看到更多的骨架可以使用mvn的交互式Interactive generate Goal创建指令:mvn archetype:generate
// Creating a simple java application
mvn archetype:create -DgroupId=[your project's group id] -DartifactId=[your project's artifact id]
// Creating a webapp
mvn archetype:create -DgroupId=[your project's group id] -DartifactId=[your project's artifact id] -DarchetypeArtifactId=maven-archetype-webapp
// Creating a site
mvn archetype:create -DgroupId=[your project's group id] -DartifactId=[your project's artifact id] -DarchetypeArtifactId=maven-archetype-site-simple
// Creating a mojo
mvn archetype:create -DgroupId=[your project's group id] -DartifactId=[your project's artifact id] -DarchetypeArtifactId=maven-archetype-mojo
// Creating a portlet
mvn archetype:create -DgroupId=[your project's group id] -DartifactId=[your project's artifact id] -DarchetypeArtifactId=maven-archetype-portlet

现在想介绍的是多模块的工程的构建。
?
典型的多模块划分,即按MVC的分层方式来构建多个模块,如工程包括web,business,core3个模块。好我们先看看主工程的pom中应添加些什么,请注意红色文字部分
1.主工程的pom文件中内容:
?
??? <modelVersion>4.0.0</modelVersion>
??? <groupId>com.your-company.xxxx</groupId>
??? <artifactId>xxxx</artifactId>
??? <packaging>pom</packaging>
??? <version>1.0</version>
??? <name>xxxx Project</name>
??? <url>http://maven.apache.org</url>
?
??? <!-- 工程所包含的模块 -->
??? <modules>
??? ??? <module>xxxx-core</module>
??? ??? <module>xxxx-business</module>
??? ??? <module>xxxx-web</module>
??? </modules>
?
2.Web模块的pom文件:
?
??? <!-- 父级的pom文件位置 -->
??? <parent>
??? ??? <groupId>com.your-company.xxxx</groupId>
??? ??? <artifactId>xxxx</artifactId>
??? ??? <version>1.0</version>
??? ??? <relativePath>../pom.xml</relativePath>
??? </parent>
?
??? <groupId>com.your-company.xxxx</groupId>
??? <artifactId>xxxx-web</artifactId>
??? <packaging>war</packaging>
??? <version>1.0</version>
??? <name>xxxx-web/name>
??? <url>http://maven.apache.org</url>
?
??? <dependencies>
??? ??? <!-- Application Dependencies -->
??? ??? <!-- Web层所依赖的上两层模块 -->
??????? <dependency>
??? ??? ??? <groupId>com.your-company.xxxx</groupId>
??? ??? ??? <artifactId>xxxx-core</artifactId>
??? ??? ??? <version>${version}</version>
??? ??? </dependency>
??? ??? <dependency>
??? ??? ??? <groupId>com.your-company.xxxx</groupId>
??? ??? ??? <artifactId>xxxx-business</artifactId>
??? ??? ??? <version>${version}</version>
??? ??? </dependency>
??????? ...
??? <dependencies>
3.完成后,mvn eclipse:eclipse后的文件目录为:
?
xxxx
├─xxxx-core
│? ├─pom.xml
│? ├─.settings
│? ├─src
│? │? ├─main
│? │? │? ├─java

│? │? └─test
│? │????? ├─java
│? │????? └─resources
