This is a sample Kotlin compiler plugin I designed under my ramblings on JVM bytecode instrumentation.

This is a very basic plugin. All it does is to automatically generate the code to return the full qualified class name for custom views to be properly viewed and identified on tools such as the uiautomatorviewer. I called it inspekt.

Installation

Since this is just an exploratory project and not really that useful (yet) , this plugin is not published anywhere. Instead, if you're willing to give it a try for any reason, just build the project:

./gradlew clean build

And install it on your local maven repository:

./gradlew :gradle-plugin:install :compiler:install

Add the following dependency to your project-level build.gradle file:

buildscript {
    // Does not work on Kotlin versions 1.4.X and above
    ext.kotlin_version = "1.3.61"
    repositories {
        ...
        mavenLocal()
    }
    dependencies {
       ...
       classpath "inspekt:gradle-plugin:0.0.1"
    }
}

allprojects {
    repositories {
        ...
        mavenLocal()
    }
    apply plugin: 'inspekt'
}

This would apply it to all subprojects. That's all what's needed.

The plugin is enabled by default. You can disable it for specific modules by adding to each build.gradle file:

inspekt {
    enabled = false
}

Roadmap

There are plans to add features whenever I have some time. The basic idea is developing this plugin to make inspection tooling more extensible.
