## Build environment requirements

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 

        when:
        succeeds scaladoc, "-i"

        then:
        // Looks like
        // Started Gradle worker daemon (0.399 secs) with fork options DaemonForkOptions{executable=/Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk/Contents/Home/bin/java, minHeapSize=null, maxHeapSize=234M, jvmArgs=[], keepAliveMode=DAEMON}.
        outputContains("maxHeapSize=234M")
    }
