Thanks a lot for this @sullis and sorry this has been sitting here so long. I'll probably just merge this in so we can iterate and improve on this. I'd like to get some of the other prs addressed, but want to make sure CI is in place.

Why did you remove CircleCI configuration?
Build failed https://app.circleci.com/pipelines/github/scoverage/scoverage-maven-plugin/2/workflows/337a503a-29f0-4966-b98b-80b8b799682b/jobs/111

Every other project in scoverage is off of CircleCI and all on GitHub actions. Imo it's best to align this, and seeing that it's quite a bit more popular, people will be familiar with it. This repo hasn't seen any action in a while, and I'd like to get some of the prs taken care of, so I'd like to migrate to GitHub actions. I plan on fixing the build with actions to it's ✅, but haven't yet had the time.

Is this something you don't want?

I'm OK with the change. Disabled CircleCI integration.
