Could not find com.android.tools.build:gradle:4.4

Question

I just migrated gradle from 3.0.1 to 4.4. Now Android Studio showing gradle build failed showing below errors.

Caused by: org.gradle.internal.resolve.ModuleVersionNotFoundException: Could not find com.android.tools.build:gradle:4.4. Searched in the following locations: https://jcenter.bintray.com/com/android/tools/build/gradle/4.4/gradle-4.4.pom https://jcenter.bintray.com/com/android/tools/build/gradle/4.4/gradle-4.4.jar https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/4.4/gradle-4.4.pom https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/4.4/gradle-4.4.jar

Project level build.gradle file is following below

 buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        //classpath 'com.android.tools.build:gradle:3.0.1'
        //replaced by 4.4 below
        classpath 'com.android.tools.build:gradle:4.4'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
        mavenCentral()
        jcenter()
        google()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Project structure is shown below.

Answer 1

You mixed up with plugin version and distributionUrl. Plugin version should be classpath 'com.android.tools.build:gradle:3.0.1' or com.android.tools.build:gradle:3.1.0. Read Android Plugin for Gradle Release Notes.

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
    }
}

And distributionUrl to GradleWrapper.

distributionUrl = https\://services.gradle.org/distributions/gradle-4.4-all.zip

Currently latest Version 3 gradle plugin available on android for which you have to use classpath 'com.android.tools.build:gradle:3.1.0'.
To be up to date see Configure Your Build.

Guess you mixed up Gradle and Android Gradle Plugin regarding their versions?

The latest Android Gradle Plugin is v4.0.0 as of April 2020, which maps to Gradle v6.1.1.
