buildSrc/src/kotlin/main/*

but depending on what you're doing, there's probably a better way (version catalogs, convention plugins, included builds)

Thank you so much @ephemient! Managed to make it work with

buildSrc/src/java/main/*.java

as well, it is exactly the behaviour I was looking for.

ah right, Kotlin won't work out of the box in

buildSrc

unless your

buildSrc/build.gradle.kts

contains

plugins {
    `embedded-kotlin` // or `kotlin-dsl`
}

or the equivalent in Groovy

Wait what? Gradle supports scala buildfiles??
