1. maven 3 特性 http://www.developer.com/java/article.php/3908561/Top-10-New-Features-in-Maven-3.htm
   maven 标准目录 
   src -main
             –bin 脚本库
             –java java源代码文件
             –resources 资源库，会自动复制到classes目录里
             –filters 资源过滤文件
             –assembly 组件的描述配置（如何打包）
             –config 配置文件
             –webapp web应用的目录。WEB-INF、css、js等
         -test
             –java 单元测试java源代码文件
             –resources 测试需要用的资源库
             –filters 测试资源过滤库

    MVN环境
              apache-maven-3.0.4-bin.tar.gz
              下载解压，配置MAVEN_HOME 和 添加至PATH
    构建工程
   >构建app应用
   mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false
   >构建web应用
   mvn archetype:generate  -DgroupId=com.byread -DartifactId=blogweb -DarchetypeArtifactId=maven-archetype-webapp  -DinteractiveMode=false
    命令
   >查看版本|测试|清理
     mvn -v
     mvn test  
     mvn clean
   >执行项目
     mvn package  -Dmaven.test.skip=true  
     mvn install -Dmaven.test.skip=true  
     mvn install assembly:assembly  
   >转eclipse项目 
     mvn eclipse:eclipse 
   >运行函数 
      mvn exec:java -Dexec.mainClass=com.test.Main  
      java -cp test.jar com.test.Main 
   >查看插件
      mvn help:describe -Dplugin=exec -Dfull
   >查看整个项目依赖的类树结构
      mvn dependency:tree
   >运行jetty
     1. mvn jetty:run
         mvn jetty:run -Djetty.port=8082  
     2.pom配置
   <plugin>
       <groupId>org.mortbay.jetty</groupId>
       <artifactId>jetty-maven-plugin</artifactId>
       <version>8.0.1.v20110908</version>
       <configuration>
           <scanIntervalSeconds>10</scanIntervalSeconds>
           <webAppConfig>
               <contextPath>/demo</contextPath>
           </webAppConfig>
       </configuration>
   </plugin>
   发布项目
   >发布到本地 
   mvn install:install -file -Dfile=[D:/opensource/dbunit-2.2/dbunit-2.2.jar] -DgroupId=[dbunit] -DartifactId=[junitperf] -Dversion=2.2 -Dpackaging=jar
   >发布到远程
   mvn deploy:deploy -file -DgroupId=[staticComparison] -DartifactId=[static-comparison] -Dversion=2.0 -Dpackaging=jar -Dfile=c:/staticComparison_2.0.jar -Durl=file:Y:\repo
   多模块项目

   注意：
   运行时，一定要  mvn  package -Dmaven.test.skip=true
   否则，请配置junit包！
