Migrating from Gradle using Groovy script to Kotlin script

Steps:

• clone the gradle-script-kotlin project
• copy/paste from the cloned project to your project:
• build.gradle.kts
• gradlew
• gradlew.bat
• settings.gradle
• update the content of the build.gradle.kts based on your needs, you can use as inspiration the scripts in the project just cloned or in one of its samples
• now open Intellij and open your project, in the explorer window, it should be recognized as a Gradle project, if not, expand it first.
• after opening, let Intellij works, open build.gradle.kts and check if there are any error. If the highlighting is not working and/or is everything marked red, then close and reopen Intellij
• open the Gradle window and refresh it

If you are on Windows, you may encounter this bug, download the full Gradle 3.3 distribution and use that instead the one provided. Related.

OSX and Ubuntu work out of the box.

Small bonus, if you want to avoid all the hassle of publicing on Maven and similar, use Jitpack, the lines to add are almost identical compared to Groovy. You can take inspiration from this project of mine.
