In a paper I am working on for my Uni project, I need to analyze maven packages. I need the pom files of these packages to then parse them and get the necessary data to create a graph and analyze it.

I looked all over the internet but found nothing on this Luke Lucene project and documentation seems extremely old. Are there some other ways I can download pom files from packages released in this index? https://repo.maven.apache.org/maven2/.index/
