Error when adding buildFeatures in build.gradle file

Question

I am trying out compose which is a new feature in Andorid jetpack. Below is my code. I am adding buildfeatures in build.gradle file of app, not in the root folder.

android {
    compileSdkVersion compileSDKVer
    buildToolsVersion buildToolsVer
    defaultConfig {
        applicationId "com.sample.slothyhacker.jetpackcompose"
        minSdkVersion minSdkVer
        targetSdkVersion targetSdkVer
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }

    buildFeatures {
        // Enables Jetpack Compose for this module
        //compose true
    }

    compileOptions {
        // Set both the Java and Kotlin compilers to target Java 8.
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    kotlinOptions {
        jvmTarget = "1.8"
    }
}

But my project is giving me a compile error. I would really appreciate if someone can put some light on what am doing wrong.

Could not find method buildFeatures() for arguments [build_7yf57wk394cperk1t82v120yf$_run_closure1$_closure5@78c292be] on object of type com.android.build.gradle.internal.dsl.BaseAppModuleExtension.

I caught this error when I tried to add Jetpack to my existing app. I followed Suraj's answer, even used the newest Kotlin gradle plugin, and couldn't exactly figure out what was wrong. I also followed the official setup guide and it didn't work. Everything seemed okay, but nothing helped.

Installing Android Studio 4.0 canary didn't help either.

Turns out, it's not enough to just include certain dependencies – you need specific versions or higher. I was using an older Android Gradle plugin: 3.5.3. Upgrading to 4.0.0-alpha07 fixed the error:

classpath 'com.android.tools.build:gradle:4.0.0-alpha07'

Make sure to check your dependencies if you're adding Jetpack to an existing app
