Note: the prior GMS Gradle plugin [oss-licenses-plugin](https://github.com/google/play-services-plugins/tree/master/oss-licenses-plugin) was, despite belonging to the GMS service stack, open-source. However it was a bit clunky to use and it does not keep up with the newest Gradle plugin standards, so it got replaced by Mike Penz' AboutLibraries library/plugin. This plugin allows me to define custom licenses and have an JC integration without needing to maintain much code, which is always a plus.
