Gradle Kotlin DSL

Gradle’s Kotlin DSL(domain-specific languages) provides an alternative syntax to the traditional Groovy DSL with an enhanced editing experience in supported IDEs, with superior content assist, refactoring, documentation, and more.

We can make a custom file to maintain configuration params and dependency version for the whole project in a single configuration file.

Step 1: Create a folder structure under the buildSrc folder:

Step 2: Add file build.gradle.kts

import org.gradle.kotlin.dsl.`kotlin-dsl`

plugins {
    `kotlin-dsl`
}

repositories {
    jcenter()
}

import org.gradle.kotlin.dsl.`kotlin-dsl`

plugins {

`kotlin-dsl`

}

repositories {

jcenter()

}

Step 3: NowAdd build configuration file Dependencies.kt

object ApplicationId {
    val id = "com.demo.android"
}

object Modules {
    val app = ":app"
    val navigation = ":navigation"
    val network = ":network"
    val sample = ":sample"
}

object Releases {
    val versionCode = 100
    val versionName = "1.01"
}

object Versions {
    val gradle = "3.4.2"
    val compileSdk = 28
    val minSdk = 21
    val targetSdk = 28
    val appcompat = "1.0.2"
    val design = "1.0.0"
    val cardview = "1.0.0"
    val recyclerview = "1.0.0"
    val ktx = "1.0.0-alpha1"
    val kotlin = "1.3.41"

}

object Libraries {
    val kotlin = "org.jetbrains.kotlin:kotlin-stdlib-jdk7:${Versions.kotlin}"
    val ktx = "androidx.core:core-ktx:${Versions.ktx}"
    val appcompat = "androidx.appcompat:appcompat:${Versions.appcompat}"
    val design = "com.google.android.material:material:${Versions.design}"
    val cardview = "androidx.cardview:cardview:${Versions.cardview}"
    val recyclerview = "androidx.recyclerview:recyclerview:${Versions.recyclerview}"
}

object ApplicationId {

val id = "com.demo.android"

}

object Modules {

val app = ":app"

val navigation = ":navigation"

val network = ":network"

val sample = ":sample"

}

object Releases {

val versionCode = 100

val versionName = "1.01"

}

object Versions {

val gradle = "3.4.2"

val compileSdk = 28

val minSdk = 21

val targetSdk = 28

val appcompat = "1.0.2"

val design = "1.0.0"

val cardview = "1.0.0"

val recyclerview = "1.0.0"

val ktx = "1.0.0-alpha1"

val kotlin = "1.3.41"

}

object Libraries {

val kotlin = "org.jetbrains.kotlin:kotlin-stdlib-jdk7:${Versions.kotlin}"

val ktx = "androidx.core:core-ktx:${Versions.ktx}"

val appcompat = "androidx.appcompat:appcompat:${Versions.appcompat}"

val design = "com.google.android.material:material:${Versions.design}"

val cardview = "androidx.cardview:cardview:${Versions.cardview}"

val recyclerview = "androidx.recyclerview:recyclerview:${Versions.recyclerview}"

}

Now you have completed DSL set up and you can use Dependencies.kt file configuration in your project as

dependencies {
    implementation project(Modules.app)
    implementation project(Modules.navigation)

    implementation Libraries.design
    implementation Libraries.cardview
    implementation Libraries.appcompat
    implementation Libraries.recyclerview
    implementation Libraries.koinAndroid
}

dependencies {

implementation project(Modules.app)

implementation project(Modules.navigation)

implementation Libraries.design

implementation Libraries.cardview

implementation Libraries.appcompat

implementation Libraries.recyclerview

implementation Libraries.koinAndroid

}
