How to fix the build?

Hello! I'm enjoying this library very much.

However, building it gives this:

% ./gradlew clean

> Task :buildSrc:compileKotlin FAILED

Can this either be fixed, or could you document what extra setup steps I need to do? I'd appreciate it!

Sorry, I realize now that this problem may not be specific to your project. I work in an environment where builds are hermetic and so I never really know what aspects of my own environment a build might be sensitive to.

I'm on macos_arm64. From backing up to JDK 11 I at least get a different error, which seems to be something missing in my Xcode installation...
