This is an example project that shows how to create a Kotlin Compiler Plugin. At compile time a gradle plugin will trigger the compiler plugin. The plugin will print "Hello from" and the name of the file that is being compiled, as a compiler warning to the terminal log.
ℹ️ Please be aware that the Kotlin Compiler still doesn’t have any stable API and there is no backwards compatibility guaranteed. Kotlin versions above 1.3.72 can have all totally different API.
- Inside the project folder run
./gradlew clean build
The plugin is only active when the build cache is changed. This is why you need to run "clean" before building, when you want to see the log output again.
- app - A Kotlin Multiplatform project which applies a gradle plugin(compiler.plugin.helloworld) whichs triggers the compiler plugin.
- kotlin-compiler-native-plugin - This module contains the Kotlin Compiler Plugin for native targets
- kotlin-compiler-plugin - This module contains the Kotlin Compiler Plugin for JVM/JS targets
- gradle-plugin - This module contains the gradle plugin which trigger the two compiler plugins
