Update gradle to 4.1 in Android Studio

Question

My Android Studio shows me next window every start up

So I decided to update it. After click update in Android Studio build.gradle for a project opens. I change gradle version to 4.1 as suggested at pop up and click synchronize in Android Studio

classpath 'com.android.tools.build:gradle:4.1'

I see next error

Error:Could not find com.android.tools.build:gradle:4.1.  
Searched in the following locations:
file:/C:/Program Files/Android/Android Studio/gradle/m2repository/com/android/tools/build/gradle/4.1/gradle-4.1.pom
file:/C:/Program Files/Android/Android Studio/gradle/m2repository/com/android/tools/build/gradle/4.1/gradle-4.1.jar

https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/4.1/gradle-4.1.jar

I checked C:\Program Files\Android\Android Studio\gradle\m2repository\com\android\tools\build\gradle and there is no 4.1 folder inside. Do I need to install it manually?

Answer 1

Android-gradle-plugin version 4.1 not released yet.

(Don't be confuse with Gradle and Android plugin for gradle)

Currently Android Studio 3.0.1 using Gradle-4.1 and Android-gradle-plugin 3.0.1

How I update gradle manually in Android Studio 3.0.1 :

1. Find gradle folder inside your project

   Open gradle-wrapper.properties and change

   distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip
   

2. Open root build.gradle file and change in buildscript

   classpath 'com.android.tools.build:gradle:3.0.1'
   

3. Additionally you need to add google() repo link in project repositories list and buildScript repo list.

   repositories {
       mavenLocal()
       mavenCentral()
       jcenter()
       google()        //<-   Add
   }
