如何弄清楚maven的pom.xml中的依赖关系依赖的jar？

des*_*pot 6 spring dependencies maven-2 pom.xml maven

我对如何找出maven的pom.xml中的依赖依赖的罐子非常感兴趣.

我习惯在我的Web应用程序项目中自己添加库(jars).当我尝试配置spring 3.0样本时,我遇到了这种需求.我真的不喜欢所有东西都必须经过使用spring 3.0.x的maven.在这一点上,我似乎无法深入挖掘maven的依赖迷宫,并且学习它看起来像是必须的.但我真的很感激,如果有人能告诉我一个方法,我可以找到这个信息.

例如,对于以下pom.xml,我想知道artifactId spring-context的依赖关系取决于什么.(我可以看到它依赖于commons-logging,因为样本的创建者排除了它 - 想要使用slf4j而不是commons-logging.).我想通过artifactId spring-context找出依赖关系的其余依赖关系,其余的依赖关系也是如此!我怎样才能做到这一点？

亲切的问候,
暴君

编辑(一些跟进肖恩给出的答案):
1)下载maven(我下载的版本2.2.1)并按照那里给出的安装说明进行操作.
2)比打开命令提示符并转到pom.xml目录
3)按照建议执行"mvn dependency:tree"命令.(我尝试使用-DoutputFile ="somePath"或-Dinclude =弹簧上下文- >它不在路径中呈现的文件以书面形式和它被选择的所有依赖关系,而不是弹簧上下文-不管一般命令将满足).等待一段时间让系统下载所有需要的信息,最后你会得到这样的东西:

您可以使用Jarvana下载jar(只需输入jarvana + jar的名称),也可以使用svn checkout命令.

休眠-验证:罐子:4.1.0.Final在Jarvana返回一个错误(没有4.1.0 Final版- >仅4.0.2最终
也org.codehaus.jackson映射器-翔升1.6.4找不到 - 只有1.6.2(与jackson-core-asl相同).我假设如果你使用maven来构建你的项目会发生同样的情况.

在我包含了所有需要的jar之后,我在调试模式下启动了服务器并且发生了这种情况:

TIME org.apache.catalina.loader.WebappClassLoader validateJarFile
INFO: validateJarFile(C:\somePath\mvc-ajax3.0\WEB-INF\lib\jsp-api-2.1.jar) - jar not loaded. 
See Servlet Spec 2.3, section 9.7.2. Offending class: javax/servlet/jsp/JspPage.class

这意味着(我认为)这些罐子被发现两次.删除它们为我完成了这项工作.像pom.xml这样的接口对此示例无效.

我花了太多时间手动下载罐子并"打击"所有项目配置,所以我想最好学习一些Maven,如果你试图从Spring 3.0开始.

执行mvn dependency:tree,它将列出所有项目的依赖项.
