In Maven 2, how do I know from which dependency comes a transitive dependency?
提问by paulgreg
I would like to know which dependency described in my pom.xml brings a transitive dependency in my target directory.
我想知道我的 pom.xml 中描述的哪个依赖项在我的目标目录中带来了传递依赖项。
To be more precise, I have the library "poi-2.5.1-final-20040804.jar" in my WEB-INF/lib directory and I would like to know which dependency in my pom.xml brings that.
更准确地说，我的 WEB-INF/lib 目录中有库“poi-2.5.1-final-20040804.jar”，我想知道我的 pom.xml 中的哪个依赖项带来了它。

To add to @David Crow, here's a dependency:tree examplefrom the Maven site:
要添加到@David Crow，这里有一个来自 Maven 站点的依赖项：树示例：
mvn dependency:tree -Dincludes=velocity:velocity
might output
可能会输出
[INFO] [dependency:tree]
[INFO] org.apache.maven.plugins:maven-dependency-plugin:maven-plugin:2.0-alpha-5-SNAPSHOT
[INFO] \- org.apache.maven.doxia:doxia-site-renderer:jar:1.0-alpha-8:compile

If you run maven with "-x" switch, it will print out plenty of diagnostics, I guess the relevant dependency path can be picked up from there.
如果您使用“-x”开关运行 maven，它将打印出大量诊断信息，我想可以从那里获取相关的依赖路径。

The dependency information is also included in the Project Information/Dependencies report if you have maven generate a site for the project, using mvn site.
如果您已使用 maven 为项目生成站点，则依赖项信息也包含在项目信息/依赖项报告中。

If you use eclipse and the m2eclipse pluginthen there is a graphical version of dependency tree where you can filter by scope etc.
如果您使用 eclipse 和m2eclipse 插件，那么有一个图形版本的依赖树，您可以在其中按范围等进行过滤。
