Answer 1

You can use the Maven Dependency Plugin to analyze the dependencies of you POM.

mvn dependency:list -DoutputAbsoluteArtifactFilename=true -DoutputFile=dependencies.txt

Answer 2

A dependency is not aware of its "source repository" which might not be unique so you won t be able to get the "source URL" of a dependency without actually resolving it. One way to do that (without writing code using Maven internal APIs) would be to use dependency:purge-local-repository. From the Maven Dependency Plugin documentation:

dependency:purge-local-repository tells Maven to clear all dependency-artifact files out of the local repository, and optionally re-resolve them.

Run that command and redirect the output to a file for post-processing:

mvn dependency:purge-local-repository > raw.txt

As I just mentioned, if you are using several repositories, you might need to do some post processing to separate the "successful" download from "failed" attempts. Here is a sample regex on Rubular that might be helpful to implement such a post-processing (I provided some content illustrating the "problem").
