Maven2 应用

1.我用

mvn -DgroupId=com.sixconnex -DartifactId=sixconnex -Dversion=1.0 
	-DarchetypeArtifactId=maven-archetype-webapp 

建了个web项目.并且创建了目录结构如下:

src/main/java
src/main/recourses
src/main/config
src/main/filters
src/main/webapp/WEB-INF/classess
src/main/site
src/test/java
src/test/resources
target/classes
target/test-classes

2.我运行 mvn eclipse:eclipse -Dwtpversion=1.5 生成eclipse web 项目的配置文件.

3.我将项目import入eclipse jee中,修改添加了M2_REPO的classpath variables指向local repository.

4.我的项目有依赖hibernate3 和 spring 3.0.0.RC3 的jar
pom.xml 文件如下:

	<properties>
		<spring.maven.artifact.version>3.0.0.RC3</spring.maven.artifact.version>
	</properties>

问题是:
依赖的这些jar文件是放在local repository cache 中的, eclipse开发的时候没问题,能找到jar包,
        可以当我启动Tomcat 跑程序的时候,就会出现找不到jar包的情况, 应为WEB-INF/lib下没有这些依赖的jar包,
        当我把所以的jar包都手动拷贝到WEB-INF/lib下再跑Tomcat的时候,程序就能正常的找到jar包了. 我想有没有办法
       在maven编译的时候自动将依赖的jar包放到lib目录下去, 这样我就能跑Tomcat了.

Eclipse 3.5 之前，配置Java EE Module即可；
Eclipse 3.6 +, 用 mvn eclipse:eclipse -Dwtpversion=2.0即可。
