在Maven中查看依赖关系树? [英] View a dependency tree in Maven?

问题描述

我想确保我的Maven项目中没有重复的库.我从几个不同的存储库(包括main，Spring的repo和JBoss的存储库)中引入了很多依赖项.如何查看依赖关系图，以确保不依赖单个库的多个版本?

I'd like to make sure I'm not including duplicate libraries in my Maven project. I'm pulling in quite a few dependencies from a few different repositories including main, Spring's repo, and JBoss' repository. How can I see a graph of the dependencies so I can make sure I'm not depending on multiple versions of a single library?

如果我包含诸如org.springframework:spring-core:3.0.1.RELEASE 和 org.springframework:org.springframework.spring-core:3.0.5.RELEASE之类的东西的话，那真是太可惜了，听起来确实很奇怪，因为Spring的存储库为事物命名怪异的.我该怎么做才能确保我没有重复的依赖关系?

It would be kind of a bummer if I was including something like org.springframework:spring-core:3.0.1.RELEASE and org.springframework:org.springframework.spring-core:3.0.5.RELEASE which actually do show up as different dependencies, as weird as it sounds, because Spring's repository names things weirdly. What can I do to make sure I don't have duplicate dependencies?

推荐答案

The dependency:tree maven plugin should do what you want and show the tree.

或者强制Maven2将依赖项复制到target/lib 将工件复制到target/lib目录中，该工件也应显示重复项，但是您仍然需要grep ~/.m2/repository中的所有POM，以查看哪个库正在手动将哪个版本拉入库，并且这对于大型库来说是耗时的本地存储库.

Alternatively force Maven2 to copy dependencies into target/lib to copy the the artifacts in the target/lib directory which should also show duplicates but you would still need to grep all the POMs in the ~/.m2/repository to see which library is pulling in which version manually and that would be time consuming for large local repositories.
