最近準備離職了，等著到20號離開。所以在公司里面沒有什么事情，自己研究了一下maven。以前對他的認識主要是依賴管理，而這幾天的學習，對他的plugin機制影響特別深刻。特別的是jetty插件的使用，十分方便。
首先需要下載eclipse，推薦最新的Helios版本，安裝m2eclipse插件，更新地址為：http://m2eclipse.sonatype.org/sites/m2e/0.10.2.20100623-1649/。新建一個maven項目，并且使用下面的pom文件。具體代碼如下：

在eclipse中選擇菜單run-》external tools進入，配置2個命令：jetty_run和jetty_stop。其中run命令location為$MAVEN_HOME/bin/mvn.bat，working directory選擇當前項目即可，參數輸入：-Dslf4j=false -Dlog4j.configuration=file:./target/classes/log4j.properties jetty:run。
stop命令和run命令前面2項相同，參數輸入：jetty:stop。
配置完上面的東西，你馬上可以開始一個maven+jetty項目，運行run即可訪問http://localhost:8080訪問web頁面，運行stop關閉服務器。
