Will this still pick the latest local changes If we make a change to one of the dependencies?

Yes. The key is an hash of the pom file, so if you are changing the POM you will cause the local cache to download the deps.

https://github.com/actions/setup-java#caching-packages-dependencies

This is not ultra useful because when we make our changes we usually change also the POM, however I read there should be also a partial hit cache.

So we would have at least cached the external dependencies. This is definitely a minor improvement. I will delve in build performance in following PRs.
