How to get jar file parent dependency?

Question

i have a jar file in my lib folder which is not in the pom file, so i was wondering which dependency downloaded this jar so i can exclude this jar from the dependency. please advise if there's a maven command to know which of my dependencies are downloading this jar.

Case:

i found in my classpath the jar slf4j-api-1.5.8.jar, and i want to know which dependency is downloading this jar so i can exclude this jar from the dependency.

Can't you see what the jar contains and google it to know which lbiraries uses this jar? — Adel Boutros, Jan 03 '12 at 14:03

If your dependencies are in `lib/` folder, that is certainly not maven who has put them there. Ask your team member who have committed this jar to source repository. — dma_k, Jan 03 '12 at 16:49

Look for Maven Dependency Plugin

 mvn dependency:tree -Dincludes=velocity:velocity

you can just run

 mvn dependency:tree

to see complete dependency tree. But good if you read the doc.

Jar file does not necessarily contain its dependencies. It can contain the list of first level dependencies in ClassPath property of manifest.mf that can be found under META-INF. So to find dependencies you should refer to manual (if the developer wrote it) or try to resolve them using tool like JDepend.
