## Introduction 🙋‍♂️

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.

## Usage

> :information_source: Please be aware that the Kotlin Compiler still doesn't have any stable API and there is no

> backwards compatibility guaranteed. Kotlin versions above 1.9.23 can have a 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.

### 👷 Project Structure

*  lib - A Kotlin Multiplatform project which applies a gradle plugin(compiler.plugin.helloworld) which triggers the compiler plugin.

*  compiler-plugin - This module contains the Kotlin Compiler Plugin

*  gradle-plugin - This module contains the gradle plugin which trigger the compiler plugin
