Consistent tagging across multiple projects in separate Git repositories

Question

I'm working on a product which relies on several different projects each hosted in its own Git repository. When a release is made, it would be ideal for us to consistently tag every project that is involved in building the product - this includes the core code, libraries and build tools. Is there an obvious and sensible way to tag all projects at once?

(It may be a distraction, or might be worth noting that each project is using Maven; perhaps there are plugins for managing this. If so, I've not found any.)

Answer 1

The question is a bit broad (at least for me) in its current state but the Maven Release plugin might help to do things in a consistent way. Pay a special attention to the Prepare a Release example.
