Good questions. First of all, this plugin is CI-agnostic, but it does require the project to exist in a `git` repository, whether that is in CI or on your machine. Check the github page I linked to for more instructions on how it determines what projects in a reactor are considered "changed" and need to be built versus which are not changed and will be omitted from the reactor.
In every Maven build, every dependency is checked this way: 1. If it is a project in the reactor, use the artifact of that project. 2. Otherwise, if the artifact is in the local repo, is that artifact. 3. Last resort: Download from the remote repository. There are some other rules omitted above, e.g. when to download a fresh SNAPSHOT artifact based on your chosen snapshot policy, etc., but that's the gist of it: Maven will obtain the artifact if it is not present, no further configuration needed. E.g. let's say you have one project that names 2 other projects A and B as submodules, and A depends on B. If you run `mvn install -pl A` (NOT SURE about that syntax), then Maven will look for B.jar from your local repo, and resort to checking your remote repo (e.g. Maven Central) if it's not there. But if you omit the `-pl A` part, Maven will build B, then build A using B.jar. Essentially, the plugin I linked to determines the project list based on what has changed and what has not. Maven then decides whether to use B/target/B.jar, ~/.m2/repository/.../B.jar, or to look to Maven Central. HTH.
