Maven2代比1代改进很多，其中主要强调的是--它不仅仅是个依赖包管理器!
开始先要推荐一个专讲Maven2的电子书给大家，对MAVEN学习相当有助益：Better Builds with Maven   


下面就专门介绍下Maven2对WEBAPP在管理和调试方面的支持。

1.创建项目

mvn archetype:create -DgroupId=com.mycompany.app -DartifactId=my-webapp -DarchetypeArtifactId=maven-archetype-webapp

也可参看这里

创建要注意遵循MAVEN的目录结构，尤其要注意源文件要放在main/java下：



2. POM文件的配置

这里要特别注意对resource一节的配置，因为我的SPRING以及WEB相关的XML是放在WEB-INF目录，为了在unit test的时候也能用，加入了对这些配置文件的引用。相当于加了一个classpath。

这里还有个插曲：不知为何MAVEN2里没有JTA的包，自动下载时会有提示教你如何手工通过命令加入，非常简单。

JETTY的plugin是为后面用它来调试做准备。

DWR也是目前WEB开发一个热选。

另外，为使用JAVA5代来编译，加入了maven-compiler-plugin一节。
