You can certainly do "whatever you want" to your local repo, including "moving" artifacts to a new groupId and modifying the pom.xml files to suit your needs.
Changing the groupId is not entirely uncommon -- sometimes you need to build a release of your own project but depend on a SNAPSHOT, and can't wait for a formal release of their code, so you release your own internal non-Snapshot version of the code under your own groupId. Or perhaps you have your own modifications to some open source code library and so you literally have a different artifact than what is being delivered by Central.

Hello, I have an idea, can I install jar files to local repository, and don't use the artifacts at central repository? I just use different groupId, but artifactId and version aren't changed. Namely, before start a project, I install the dependencies firstly. Because I exactly know which jar is my want, then I can set dependencies exactly. a cup of Java, cheers!
