最近准备离职了，等着到20号离开。所以在公司里面没有什么事情，自己研究了一下maven。以前对他的认识主要是依赖管理，而这几天的学习，对他的plugin机制影响特别深刻。特别的是jetty插件的使用，十分方便。
首先需要下载eclipse，推荐最新的Helios版本，安装m2eclipse插件，更新地址为：http://m2eclipse.sonatype.org/sites/m2e/0.10.2.20100623-1649/。新建一个maven项目，并且使用下面的pom文件。具体代码如下：
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

在eclipse中选择菜单run-》external tools进入，配置2个命令：jetty_run和jetty_stop。其中run命令location为$MAVEN_HOME/bin/mvn.bat，working directory选择当前项目即可，参数输入：-Dslf4j=false -Dlog4j.configuration=file:./target/classes/log4j.properties jetty:run。
stop命令和run命令前面2项相同，参数输入：jetty:stop。
配置完上面的东西，你马上可以开始一个maven+jetty项目，运行run即可访问http://localhost:8080访问web页面，运行stop关闭服务器。
