LibGdx doesn't working after updating Gradle (Android Studio 3.0)

I have recently updated android studio and gradle to the version 3.0.0 following instructions in this link https://developer.android.com/studio/build/gradle-plugin-3-0-0-migration.html
After doing this libgdx desktop project doesn't work.
It give me this error

Exception in thread "main"
Here is build.gradle file
buildscript {
repositories {
mavenLocal()
mavenCentral()
maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
jcenter()
google()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.0'
}
I only added google() to repositories and edit gradle version to 3.0.0
In gradle-wrapper.properties I added this line
distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip

Android Studio 3.0 using gradle-4.1 and com.android.tools.build:gradle:3.0.0
Gradle 4.1 is not supported yet in LibGDX, there is an issue for the same, which is now upgraded for Gradle 4.6
Currently html module using deprecated jetty plugin which is removed in Gradle 4.1 version.
However using Terminal you can run desktop module, I've not tested on windows but on Mac it's working fine.
./gradlew desktop:run
For now you can use lower version of Gradle and Andoid-gradle-plugin in Android Studio 3.0 and wait for issue to be fixed.
Downgrade Gradle version from 4.1 to 3.3
Find gradle folder inside your project, Open gradle-wrapper.properties and change distributionUrl for 3.3
distributionUrl=https\://services.gradle.org/distributions/gradle-3.3-all.zip
Downgrade Android-gradle-plugin version from 3.0.0 to 2.3.3
Open root build.gradle file and find artifact in buildscript and
change version
classpath 'com.android.tools.build:gradle:2.3.3'
Comment/delete google() from repo list inside root build.gradle file
--------------------------------------------------------------------------------
EDIT : Update LibGDX project to Gradle 4.6 - AS USER
Upgrade Gradle to 4.6 :
distributionUrl=https\://services.gradle.org/distributions/gradle-4.6-all.zip
Add Google's Maven repo in project repositories list as well as in buildScript repo list in root build.gradle file.
repositories {
//..
google()
jcenter() // Required for org.jetbrains.trove4j:trove4j library
}
Update Android Gradle Plugin :
classpath 'com.android.tools.build:gradle:3.1.3'
Known issues with the Android Gradle Plugin
Configuration on demand with Gradle 4.6 and above:
If you're using Android Gradle Plugin 3.0.x or 3.1.x with Gradle 4.6
and above, you should disable configuration on demand to avoid some
unpredictable build errors. (If you are using Android Gradle Plugin
3.2.0 or higher, you do not need to take any action to disable configuration on demand.)
Disable configuration on demand in your gradle.properties file as shown below:
org.gradle.configureondemand=false
To disable configuration on demand in the Android Studio settings, choose File > Settings (Android Studio > Preferences on Mac), select the Compiler category in the left pane, and clear the Configure on demand checkbox.
In Android Studio 3.2 Beta 1 and higher, the options for enabling configuration on demand have been removed.
Update Android buildToolsVersion to 27.0.3 and SdkVersion to 27
Remove instrumentTest.setRoot('tests') from sourceSets inside android build.gradle file
replace all compile with implementation inside root build.gradle file
New GWT Gradle Plugin added in html module, check latest build.gradle of html module.
Run your project with Run Configuration or On Terminal using gradle task.
If you're going to create new project use gdx-setup.jar of latest build.

I temporarily solve this by forcing plugin to use 2.3.3 and gradle wrapper properties file reverted to 3.3
distributionUrl=https\://services.gradle.org/distributions/gradle-3.3-all.zip
and build.gradle
dependencies {
classpath 'com.android.tools.build:gradle:2.3.3'
}
comment out the google() from repositories and tell android studio 3.0 to stop reminding you to upgrade gradle plugin to 3.0.0 for your current project.
Edit: To the person above who plagiarised my answer, shame on you!

Edit configurations -> Desktop -> In before launch change "Build" to "Build project". (use the + and - buttons).

worked with windows , in terminal you can go to the project folder and run desktop module using command .
gradlew desktop:run

Gradle build failing after update to 3.0

I've recently updated the gradle version of my project from 2.14.1 to 3.0. Since then the gradle build is failing every time with this error:
Error:Cause: org.gradle.api.internal.tasks.DefaultTaskInputs$TaskInputUnionFileCollection cannot be cast to org.gradle.api.internal.file.collections.DefaultConfigurableFileCollection
Possible causes for this unexpected error include:Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)
Re-download dependencies and sync project (requires network)The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.
Stop Gradle build processes (requires restart)Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.
I've searched google and found some solutions like this one but nothing is working. Does anyone know how to fix it?

Upgrade your gradle build tools to the latest version.
One easy way to do this is to add the latest version of the build tools as a dependency in your build.gradle file, for example:
dependencies {
classpath 'com.android.tools.build:gradle:2.2.0-beta1'
}
You can then run gradle tasks and gradle will download everything you need.
After Android Studio 2.2 stable released on Sep 19 2016 , the latest version of the build tools is 2.2.0 . So you can fix it by :
dependencies {
classpath 'com.android.tools.build:gradle:2.2.0'
}
As Android Studio 2.4 stable is not ready to release yet (May 4 2017), the latest stable version of build tools is 2.3.1 .
dependencies {
classpath 'com.android.tools.build:gradle:2.3.1'
}
If you update this build tools version to 2.3.* , you should also update gradle wrapper version to 3.3 in /yourProjectRoot/gradle/wrapper/gradle-wrapper.properties file. (i know it is not matching question Gradle build failing after update to 3.0, but i strongly suggest you to use latest build tool as google recommended)
BTW: version 2.3.1 of build tool is only exist on jCenter, not MavenCentral, so if you run into error below when run gradlew command line in terminal
Could not find com.android.tools.build:gradle:2.3.1.
Searched in the following locations:
https://repo1.maven.org/maven2/com/android/tools/build/gradle/2.3.1/gradle-2.3.1.pom
https://repo1.maven.org/maven2/com/android/tools/build/gradle/2.3.1/gradle-2.3.1.jar
just replace mavenCentral() with jcenter() like
repositories {
jcenter()
//mavenCentral()
}

For latest update of Android Studio 3.0
In gradle-wrapper.properties(File Name) change URL of distributionUrl to the following:
distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip

If you use gradle plugin 2.1.3,
It's simple to solve:
update your gradle plugin to version 2.2.0-beta1
Notes: this is a beta version, maybe you can get any other issues.
https://discuss.gradle.org/t/classcastexception-in-gradle-nightly-3-0-20160609/17979
Happy coding :)

Okay I got it working. For anyone facing the same problem the way it worked for me is as follows:
Go to your external .gradle folder (for me it was C:\Users\drilon.gradle). Inside caches and daemon folder delete all the version folder (they look like this "2.14.1", or "3.0"). Also go to wrapper -> dists -> delete everything there.
Inside your project root (for me it was C:\Users\drilon\AndroidStudioProjects\PorjectName) go to the .gradle folder and delete everything there.
Rebuild the project
EDIT:
Turns out this solution was setting the gradle version back to 2.14.1. ending0421's solution is the working one.

For latest update of Android Studio 3.3.1 below code work.
1) gradle-wrapper.properties add below line.
distributionUrl=https\://services.gradle.org/distributions/gradle-4.6-all.zip
2)build.gradle in project level add below classpath
dependencies
{
classpath 'com.android.tools.build:gradle:3.1.0'
}

if your gradle version is: 3.0.1 then use below code in your gradle-wrapper.properties distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip
if 3.1.2 then use below code in your gradle-wrapper.properties
distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip

After 1 hour R&D No Solution as worked for me...
But still i have solution follow this its work 100%
step 1: upgrade your build.gradle(Project:<your project name>)
Example : classpath 'com.android.tools.build:gradle:2.1.3' // old gradle file
classpath 'com.android.tools.build:gradle:2.3.1' // upgraded file
OR
classpath 'com.android.tools.build:gradle:3.1.0'
Step 2 : Upgrade compileSdkVersion buildToolsVersion
Example : compileSdkVersion 23 buildToolsVersion "23.0.3 // old api's
compileSdkVersion 25 buildToolsVersion "25.0.2" // upgraded api's
Step 3: upgrade gradle-wrapper.properties
Example : distributionUrl=https\://services.gradle.org/distributions/gradle-2.14.1-all.zip // old or any version
distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip // new or any version
Step 4 : finally goto build>rebuild project...
Still You face some problem commit or inbox me....
......End #Ambilpura

You should check your Gradle Plugin version and Gradle version before updating.
Check Gradle Plugin Version in your project level build.gradle file-
buildscript {
repositories {
google()
}
dependencies {
classpath 'com.android.tools.build:gradle:gradle.plugin.version'
}
}
Check Gradle Version in your gradle-wrapper.properties-
distributionUrl=https\://services.gradle.org/distributions/gradle-gradle.version.zip
At the time of this answer, below were the latest versions. You can match your versions on this page.

Simply delete everything inside gradle folder in main project folder and Rebuild the
project. It will start working.

If your gradle plugin 3.0.0 for studio version 3.0, Add this in gradle-wrapper.properties
distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip

simple answer try this...
goto build.gradle(PROJECT) and check the gradle version as shown below
'com.android.tools.build:gradle:2.1.3' or 3.0 or 3.1 or xx.xx
now open gradle-wrapper.properties see this line of code if gradle version is 2.x this the code below...
distributionUrl=https://services.gradle.org/distributions/gradle-2.14.1-all.zip
gradle-2.14.1-all.zip line of code must be same as gradle version
example:
example:
mine is 2.x so...
classpath 'com.android.tools.build:gradle:2.1.3' in build.gradle so
distributionUrl=https://services.gradle.org/distributions/gradle-2.14.1-all.zip
in gradle-wrapper.properties.
if gradle version is 3.x then
classpath 'com.android.tools.build:gradle:3.1.0' in build.gradle then
distributionUrl=https://services.gradle.org/distributions/gradle-3.14.1-all.zip
in gradle-wrapper.properties.
check this it will works

if Android Studio Android Studio 3.0 below code work.
gradle-wrapper.properties add below line.
distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip
if Android Studio Android Studio 3.1.2 below code work.
distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip
if Android Studio 3.3.1 below code work.
1) gradle-wrapper.properties add below line.
distributionUrl=https://services.gradle.org/distributions/gradle-4.6-all.zip
2) build.gradle in project level add below
dependencies {
classpath 'com.android.tools.build:gradle:3.1.0'
}

Android Gradle dependencies are not working in new update of Android
Studio
Most important thing if you are face a lot of problems :
It is applicable on plugin 7.1 or new update version
Please Try this:
Go To -> settings.gradle inside of repositories { } :
add two files as :
maven{ url("https://repo.gradle.org/gradle/libs-releases/") }
maven { url "https://jitpack.io" }
The complete structure in
settings.gradle
file as given below :
pluginManagement {
repositories {
gradlePluginPortal()
google()
mavenCentral()
}
}
dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
repositories {
google()
mavenCentral()
maven{ url("https://repo.gradle.org/gradle/libs-releases/") }
maven { url "https://jitpack.io" }
}
}
rootProject.name = "MyApp"
include ':app'
And last step, it is must be added into gradle.properties files.
android.useAndroidX=true
android.enableJetifier=true

Latest version of gradle can't be found

The latest version of Gradle is 2.14.1, right? Therefore, I have this:
gradle-wrapper.properties
distributionUrl=https\://services.gradle.org/distributions/gradle-2.14.1-all.zip
gradle.build
buildscript {
repositories {
mavenCentral()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.14.1'
}
}
But Android studio says it can't find it.

The version of the Android Gradle Build tool is completely independent of Gradle.
For example, yes, the recommended Gradle is 2.14.1 or higher, but the latest stable Android Gradle Build tool is 2.2.2
classpath 'com.android.tools.build:gradle:2.2.2'
EDIT (Mar. 2017) versions are now 3.3 or higher & build tool 2.3

It seems that you have misunderstood about Gradle and Android Gradle Build Tools.
In gradle-wrapper.properties, you can set the version about the Gradle; last 2.14.1
But in build.gradle, you set the Android Gradle Build tool; last 2.1.2
They are not the same thing.

How to use the latest gradle version in Android Studio

I've just noticed Gradle has released version 2.12 and according to the release notes the scripts should compile up to 20% faster. I'd like to upgrade to that version in Android Studio.
I'm using v1.5.1 and in the settings I've selected the "Use default gradle wrapper" option, which means that instead of using a local gradle install for every project, a specific gradle version will be used for each project. The version used is the one defined in the build.gradle file. Example:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.5.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
Now if I change that to this:
classpath 'com.android.tools.build:gradle:2.12'
then Android Studio can't find that version and throws an error. Apparently AS tries to find the binaries in a local cache first (Android Studio/gradle/m2repository) and then it tries to download it from bintray:
https://jcenter.bintray.com/com/android/tools/build/gradle/2.12/gradle-2.12.jar
Browsing the published builds it looks like the last version available here is v2.1.0-alpha1.
Why is v2.12 not in bintray yet? Is it not compatible with Android Studio?
If it were compatible, is there a way to download it and use a local install in a per-project basis? (I don't want to break older projects already in version control)

com.android.tools.build:gradle is android's plugin for gradle. It is not the same as gradle distribution. See here for release/version information of gradle android plugin: https://maven.google.com/web/index.html?q=gradle#com.android.tools.build:gradle
To change the gradle version that the plugin uses, edit the file:
<Project>/gradle/wrapper/gradle-wrapper.properties
and change this line to the gradle verison you want:
distributionUrl=http\://services.gradle.org/distributions/gradle-2.12-all.zip
Then rebuild your project.
Do keep in mind that the android plugin version you're using may not have been tested with this brand new gradle version and could potential cause unexpected issues.
android gradle plugin to Gradle version compatibility as of Feb2020
Plugin version Required Gradle version

1.0.0 - 1.1.3 2.2.1 - 2.3

3.4.0 - 3.4.1 5.1.1+
3.5.0 - 3.5.3 6.0.1+
3.6.0+ 6.0.1+

For AS 2
The latest plugin is:
classpath 'com.android.tools.build:gradle:[INSERT LATEST HERE]'
For AS 3
You should update the repositories to include google(), you also need gradle > 4.1 for that and the latest is then here:
https://developer.android.com/studio/releases/gradle-plugin.html
At time of writing that was:
buildscript {
repositories {
// Gradle 4.1 and higher include support for Google's Maven repo using
// the google() method. And you need to include this repo to download
// Android plugin 3.0.0 or higher.
google()
...
}
dependencies {
classpath 'com.android.tools.build:gradle:3.3.0'
}
}

What worked for me in addition to the above (changing the distibutionURL) was to keep my classpath as 2.0.0 in build.gradle (Modile:app):
classpath 'com.android.tools.build:gradle:2.0.0'
In File > Project Structure > Project: change 'Gradle version' to 2.12
In File > Settings > Build, Execution, Deployment > Build Tools > Gradle :
Under 'Project-level settings' section, there are 2 options:
Use default gradle wrapper (recommended)
Download gradle-2.12-all.zip from http://gradle.org/post-download-gradle/
then select 'Use local gradle distibution' and map 'Gradle home:" i.e. C:/Gradle/gradle-2.12
Note that option 2 will require you to download each gradle version update.

Try this: -
change this url according to latest version in gradle-wrapper.properties and then change gradle.
distributionUrl=https\://services.gradle.org/distributions/gradle-2.9-all.zip
Hope it helps
Thanks

You can't use the default gradle wrapper if you want to use the latest, you have to go it the settings, check "Use customizable gradle wrapper", then change in
Project/gradle/wrapper/gradle-wrapper.properties
the distributionUrl value
distributionUrl=https\://services.gradle.org/distributions/gradle-2.12-bin.zip

Gradle version 1.10 is required. Current version is 2.2.1. error(20,0) Gradle DSL method not found: 'buildTypes()'

I got the error when i importing existing project to android studio.below i attached a screenshots of error message..
We are using android studio version 1.2.2. and Our System is Windows 7 32 bit
Error:Gradle version 1.10 is required. Current version is 2.2.1.
Please Guide to us.

Check the version of gradle and gradle plugin used in your project.
In your build.gradle (this is the gradle plugin version) you can use:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.2.3'
}
}
In gradle/wrapper/gradle-wrapper.properties (this is the gradle version)
distributionUrl=http\://services.gradle.org/distributions/gradle-2.4-all.zip
There is a relation between gradle-plugin and the gradle version, and they need to be compatible.
Check these links for a full version compatibility mapping table:
