Writing Your First Kotlin Compiler Plugin
summary
Shows how to build and publish a real Kotlin compiler plugin as two modules: a Gradle sub-plugin wrapper and a Kotlin module implementing a command line processor and component registrar. Uses the Kotlin compiler embeddable API, registers a ClassBuilderInterceptorExtension, and emits JVM bytecode via objectweb ASM to inject entry/exit logging. The demo modifies a prime calculator, traces the 20,000th prime, prints parameter values and elapsed time (~6–7s), and shows packaging for Maven/JCenter so the plugin can be applied from Gradle.
