In Maven 2, how do I know from which dependency comes a transitive dependency?
I would like to know which dependency described in my pom.xml brings a transitive dependency in my target directory.
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.
To add to @David Crow, here's a dependency:tree example from the Maven site:
mvn dependency:tree -Dincludes=velocity:velocity
might output
[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
[INFO] \- org.codehaus.plexus:plexus-velocity:jar:1.1.3:compile
[INFO] \- velocity:velocity:jar:1.4:compile
If you use eclipse and the m2eclipse plugin then there is a graphical version of dependency tree where you can filter by scope etc.
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.
mvn -X dependency:tree -Dverbose |grep -C20 sonatype.aether
You can have many reports by
mvn site
One of them is the dependency report.
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.
