Kotlin wins Breakout Project of the Year award at OSCON ’19

Posted on July 18, 2019 by Andrey Breslav

Today at the O’Reilly Open Source Awards 2019, we were honored to hear that Kotlin has won the prestigious Breakout Project of the Year award, this award recognizes a project that has started “breaking out in a big way” over the past year, which we are really happy about. We want to say a massive thank you to O’Reilly OSCON for this recognition, but more importantly, we want to take a minute to thank the incredible Kotlin community who have brought the project to where it is today.

Since our first commit to the GitHub repository on the 7th of November, 2010, we have watched in awe as the open-source community has embraced the language and driven it forward with their contribution, support, and ideas which have gone into the language we are all very proud of.

There is still work to do, but as long as we have such an incredible community behind us we know we can make this language what it needs to be for developers. If you haven’t used Kotlin yet, we would love to have you try. Your contributions and feedback are what help us improve. Get involved in the evolution of the language and let’s see how far we can go together.

Again, to everyone who has helped make Kotlin the success it is today, thank you and have a nice Kotlin! :)

We are happy to announce the new and improved Kotlin/Native plugin for AppCode 2019.1! Enjoy working on Kotlin, Swift, and Objective-C projects for macOS and iOS inside the same IDE. New to AppCode?

New Kotlin/Native Projects for iOS

The Kotlin/Native plugin for AppCode adds support for Kotlin/Native projects written in Gradle.

Gradle Kotlin DSL 1.0

Posted on December 10, 2018 by Roman Belov

Paul Merlin
This is a guest blog post from Paul Merlin
software engineer for Gradle

The recently released Gradle 5.0 includes the Gradle Kotlin DSL v1.0 which is now ready for widespread use.

We want you to enjoy a build authoring experience with the benefits provided by Kotlin’s static type system in Intellij IDEA and Android Studio: auto-completion, smart content assist, quick access to documentation, navigation to source and context-aware refactoring.


To view the video in Safari you may need to install the VLC Web Browser Plugin.

In case you missed it, you can watch Paul Merlin demonstrate these benefits in the Type-safe build logic with Gradle Kotlin DSL video from KotlinConf 2018.

If you prefer the flexibility and dynamic features of Groovy, that’s totally okay — the Groovy DSL will not be deprecated.

Using the Kotlin DSL today

You can get started quickly by following the Creating New Gradle Builds guide. You can also follow one of the other guides like Building Kotlin JVM Libraries or Building Java Applications.

The Gradle Kotlin DSL Primer user manual chapter is the best place to start learning more: it will cover all the basics and answer most of your questions.

If you are working with an existing build using the Gradle Groovy DSL you’ll be interested in the Migrating build logic from Groovy to Kotlin guide.

Several community plugins now have Gradle Kotlin DSL snippets in their documentation: Spring Boot, Docker, Detekt, Kotlinter, APT, Android JUnit 5, Android Check 2, Android Play Publisher and the list goes on.

Last but not least, the Gradle documentation contains build script excerpts that demonstrate both the Groovy DSL and the Kotlin DSL. This is the best place to find how to all things with each DSL; and it covers all Gradle features.

Again, a big thank you to all who helped make this a reality!

Feedback wanted

Community involvement has been instrumental to reach 1.0. It is also crucial going forward.

We want to know what you think works well or poorly in the Kotlin DSL. Feedback on the IDE experience, logging, and everything in between is welcome. Please discuss through the Kotlin DSL issue tracker or the #kotlin-dsl channel on Gradle Community Slack (which you can join using this link).
