maven 编译配置 maven插件

模块继承方式
xxx-aggregator-->父工程，同时承担聚合模块和父模块的作用，没有实际代码和资源文件

xxx-common-->基础工程，公共的代码

<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">

  	<version>1.0-SNAPSHOT</version>
  	<relativePath>../xxx-aggregator</relativePath>
  </parent>

    <struts2.springPlatformVersion>3.1.1.RELEASE</struts2.springPlatformVersion>
  </properties>

  <dependencies>
   </dependencies>
</project>

xxx-web-->web工程放置里公共的配置文件，比如struts.xml、ssoconfig.properties等，起到聚合的作用，即把所有的web项目，打成最终的war包

  <modelVersion>4.0.0</modelVersion>

其他工程

是修改~/.m2/repository目录下settings.xml文件，添加一个profile，内容如下：

<profile>
  <id>jdk-1.6</id>
  <activation>
    <activeByDefault>true</activeByDefault>
    <jdk>1.6</jdk>
  </activation>
  <properties>
    <maven.compiler.source>1.6</maven.compiler.source>
    <maven.compiler.target>1.6</maven.compiler.target>
    <maven.compiler.compilerVersion>1.6</maven.compiler.compilerVersion>
  </properties>
</profile>

以上两个方法都比在每个pom文件中配置方便

各有各的优缺点
