Migrating build logic from Groovy to Kotlin (KTS)

Migrate all .gradle (groovy files) to .gradle.kts (Kotlin DSL)

Benefits Auto-completion and content assist Quick documentation Navigation to source Refactoring and more

Why Migrate? You already highlighted key benefits:

Better auto-completion and IDE support

Safer type checking

Easier refactoring

Improved readability

Migration Steps

1. Convert build.gradle (app-level) to build.gradle.kts Rename: mv app/build.gradle app/build.gradle.kts Translate syntax (Groovy → Kotlin):

Groovy:

plugins { id 'com.android.application' id 'kotlin-android' }

android { compileSdkVersion 34 defaultConfig { applicationId "com.example.myapp" minSdkVersion 21 targetSdkVersion 34 versionCode 1 versionName "1.0" } } Kotlin DSL:

plugins { id("com.android.application") id("org.jetbrains.kotlin.android") }

android { compileSdk = 34 defaultConfig { applicationId = "com.example.myapp" minSdk = 21 targetSdk = 34 versionCode = 1 versionName = "1.0" } } 2. Convert build.gradle (project-level) to build.gradle.kts Rename:

mv build.gradle build.gradle.kts Replace repository and classpath blocks accordingly.

Groovy:

buildscript { repositories { google() mavenCentral() } dependencies { classpath "com.android.tools.build:gradle:8.3.0" } } Kotlin DSL:

buildscript { repositories { google() mavenCentral() } dependencies { classpath("com.android.tools.build:gradle:8.3.0") } } 3. Update settings.gradle → settings.gradle.kts Rename:

mv settings.gradle settings.gradle.kts Convert:

rootProject.name = "MyApp" include(":app") 4. Update gradle.properties and local.properties No change in syntax — these are already Kotlin-agnostic.

5. Update plugins and repositories if using plugins {} block For example, in build.gradle.kts:

plugins { alias(libs.plugins.androidApplication) alias(libs.plugins.kotlinAndroid) } Common Gotchas All string values must use = "value" syntax (no :).

Use fileTree(mapOf(...)) instead of Groovy-style maps.

buildConfigField and manifestPlaceholders require type-safe syntax:

buildConfigField("String", "BASE_URL", ""https://example.com"") Final Step: Sync & Build Once migrated:

Sync Gradle from Android Studio.

Run a build to ensure no regressions.
