Automatic dependencies is one of the powerful feature of Apache maven and its one of the reason Maven is very popular in developer community. Maven resolve the dependent library from local repository which is again connected with central repository or remote repository. thus we can say that Maven has 3 kinds of repository concept.
1. Local repostory e.g $USER_HOME/.m2
2. Central repostory e.g http://repo.maven.apache.org/maven2/
3. Private repostory e.g Sonatype Nexus, Artifactory, Archiva etc.

Thanks for this practical and straightforward guide — setting up Sonatype Nexus can feel a bit overwhelming at first, but your step-by-step explanation really demystifies the process. I especially appreciated how you didn’t just list the commands, but took the time to explain why each configuration step matters, from repository setup to managing security and access controls. Seeing real examples made it feel much more approachable, especially for someone who’s still building confidence with artifact management. One thing that would make this even more helpful is a quick section on common issues people run into after the initial setup and how to troubleshoot them — that’s usually where I get stuck! Overall, this feels like a very useful resource for anyone getting started with Nexus and looking to build a solid foundation — thanks again for sharing!
