Let's say you have a large distributed deployment where the servers need to talk to each other using some protocol. You have them configured to keep talking with servers of the same major + minor version number. So a server running "3.3.233" may still talk with one that has "3.3.120" - the protocol is guaranteed to not have changed in these versions.

And not imagine that you need to deploy a drastic API change - so the new version of the servers will be "3.4.0". You can't afford to bring the system down for the deployment. But as the servers are configured to only talk with compatible versions - you're in luck. You can start the deployment process and each node, one by one will be replaced with the new version - the old servers simply stop communicating with them, and the new versions start talking with each other until only the "new" nodes are left.

Using this plugin, you can easily expose the information needed - based on git tags for example.

One might say that this is usually accomplished by using `${project.version}` and I generally would agree, but maybe tags would fit your use case better than a plain version. :-)
