What does purge-local-repository actually purge?

Question

I am running the following command from within a maven project directory:

mvn dependency:purge-local-repository

What is the expected behavior?<

Answer 1

Following

http://maven.apache.org/plugins/maven-dependency-plugin/purge-local-repository-mojo.html

we that

dependency:purge-local-repository

removes the project dependencies from the local repository, and optionally re-resolve them.
