As per #1

I haven't actually tested this because it's a bit of a pain to get travis working on a new repo - any way you can easily do a test on your end?

[jonashackt]

I migrated the repo to travis-ci.com - because, all repos will be migrated there. But sadly (as described also here codecentric/spring-boot-admin#1581), my credits are below 0 - and I can't run Travis builds anymore. Also an email didn't change that fast - so I'am unsure, when I will be able to test your PR 😢

Well, fair enough - I'm not using it either right now, for similar reasons.

I wonder how hard it is to get this working on Github Actions. I guess I'll give that a try next time I'm back on that project.

@zorbathut it's much easier on GitHub Actions: https://github.com/jonashackt/vagrant-github-actions I migrated all my projects nearly, see https://stackoverflow.com/a/66261102/4964553 also.
