This repository is using [Gradle toolchains](https://docs.gradle.org/current/userguide/toolchains.html) feature
to select and auto-provision required JDKs from [AdoptOpenJdk](https://adoptopenjdk.net) project.

Alternatively, it is still possible to only provide required JDKs via environment variables 
(see [gradle.properties](./gradle.properties#L5) for supported variable names). To ensure Gradle uses only JDKs
