// Generates gradle/gradle-daemon-jvm.properties. Any vendor's JDK 21 can run the daemon, so CI's
// setup-java JDK and Android Studio's JBR are used as they are; a machine without one downloads
// Adoptium's Temurin release directly rather than through the api.foojay.io index. Adoptium has no
// FreeBSD or other Unix builds, so those get the Linux ones, as Gradle's own foojay lookup does.
