Android Studio – Gradle sync error on gradle-diagnostics-X.X.X.jar

Question

To solve the Gradle sync error, open gradle-wrapper.properties file and update the Gradle wrapper distribution version from:

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

To:

Android Studio 3.4
distributionUrl=https\://services.gradle.org/distributions/gradle-5.1.1-all.zip
Android Studio 2.3 distributionUrl=https\://services.gradle.org/distributions/gradle-2.3-all.zip
Android Studio 2.2 distributionUrl=https\://services.gradle.org/distributions/gradle-2.14.1-all.zip
Android Studio 2.1 distributionUrl=https\://services.gradle.org/distributions/gradle-2.12-all.zip
Android Studio 2.0 distributionUrl=https\://services.gradle.org/distributions/gradle-2.10-all.zip
Android Studio 1.5 distributionUrl=https\://services.gradle.org/distributions/gradle-2.8-all.zip
Android Studio 1.3 distributionUrl=https\://services.gradle.org/distributions/gradle-2.4-all.zip

You can find the latest Gradle wrapper version visiting:
https://services.gradle.org/distributions/

EDIT:
As a side note, as @SeBsZ suggests,
the official repository of the Android Gradle plugin switched from MavenCentral to jCenter (see Bintray blog post).

Make sure your project build.gradle file contains the new repository and the new classpath:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.0'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

This is not strictly related to the question problem, but since we are already migrating to the new IDE preview it’s better to make sure everything is in place.
