In the root directory of your project, create the following directory path: buildSrc/src/main/kotlin. We’ll instead use a buildSrc module to create an external store for these globally-needed variables. We can use t('constraint_layout_version', '1.1.3') with ('constraint_layout_version') but this doesn’t give us the benefit of autocomplete for our properties, since they need to be accessed via those key strings. In Groovy, we had access to the ext object, which allows us to set variables that can be accessed from any of the inheriting Gradle scripts (this is often used to set version numbers for various dependencies).

If Android Studio ever tells you that “There are new script dependencies available” via a pop-down at the top of the window, choose the Enable auto-reload option to automatically apply them. Do a Gradle sync now, and at the end of every section below.

Of course, this will cause a lot of red syntax highlighting, since we haven’t actually converted everything to Kotlin yet, but we’ll get there. Rename the file names from adle to to indicate that they’re now Kotlin script files. Now we’ve gotten the scripts as close as possible to Kotlin syntax while still being Groovy, so we’re ready to actually convert the files to Kotlin scripts instead of Groovy scripts. In your app’s gradle-wrapper.properties file, change the Gradle version to 5.0 so that you’ll have the stable 1.0 version of Gradle Kotlin: Use the right version of Gradleĭepending on the default version of Gradle for your version of Android Studio, your project may have a version of Gradle from before Gradle Kotlin DSL was fully supported. We’ll first make some minor syntactical changes to our Groovy scripts to inch them closer to their eventual Kotlin forms, so that when we actually change the file extension, it won’t have as many errors. To continue past this, we’ll convert the default Gradle scripts to use Kotlin instead. When you create a project in Android Studio, it creates a Gradle script using Groovy by default. Plus, since we use Kotlin for day-to-day development on Android apps, editing those Gradle files isn’t as much of a cognitive load since we’re familiar with the language’s syntax. Since Kotlin is statically typed, it’s simpler for the IDE to fill in helpful hints about the code. Furthermore, since Gradle scripts are the only thing I typically see Groovy in, the syntax is way more difficult for me to parse than that of Kotlin, which I use every day during app development.īy writing our Gradle scripts in Kotlin instead of Groovy, we can solve both these problems.

Groovy is dynamically typed, so Android Studio has a tough time providing you with intelligent hints about what methods you can call, what parameters they take, and when you’ve done something wrong. I don’t know about you, but editing Gradle Groovy files is not my favorite part about Android development.

The full feature set of Gradle Kotlin DSL is supported on less IDEs than Groovy, but Android Studio and IntelliJ IDEA support everything we need, so most Android developers shouldn’t have a lot of issues. This has all of your favorite functions and assignments from the Gradle Groovy DSL, but now in Kotlin. Gradle Kotlin DSL is a domain specific language built with the express purpose of defining Gradle build plans. The folks at Gradle recently released version 5.0, which means that us Android developers now have access to Gradle Kotlin DSL v1.0! This means that we can write Gradle build scripts in our favorite language, Kotlin.
