IMHO the antipattern here is the idea that "mvn install" is bad. But let's take it step by step. For simplicity sake, let's ignore remote deploys/downloads for now. Also, let's assume a developer workstation for the same reason (simplicity).
Q: which one of your commit is your snapshot in your local repository from? A: the last one you `mvn install`-ed? Q: how can you tell? A: Your build should be reproducible ( https://maven.apache.org/guides/mini/guide-reproducible-builds.html) so you can sha target/XXX.jar and local repo? But if unsure, just `mvn install` :D Maven does not require anything to install, or at least, am not getting what you are saying. OTOH, you DO need to install, if you plan to deploy (but, we can exclude this part, as we agreed, let's stick to developer workstation case, and developer do not deploy, CI is).
