Is there a simple way to remove unused dependencies from a maven pom.xml?

I have a large Maven project with many modules and many pom.xml files. The project has changed and I suspect the pom's contain some unnecessary dependencies. Is there is a command which removes any unused dependencies from a pom?

The Maven Dependency Plugin will help, especially the dependency:analyze goal:

dependency:analyze analyzes the dependencies of this project and determines which are: used and declared; used and undeclared; unused and declared.

Another thing that might help to do some cleanup is the Dependency Convergence report from the Maven Project Info Reports Plugin.

You can use dependency:analyze -DignoreNonCompile

This will print a list of used undeclared and unused declared dependencies (while ignoring runtime/provided/test/system scopes for unused dependency analysis.)

## Be careful while using this, some libraries used at runtime are considered unused
