Cannot find AGP version in build files & empty Android Gradle Plugin Version

Android Studio Upgrade Assistant recommends to update Android Gradle Plugin from version 7.0.0. to x.x.x. However, the problem is that it alerts "Cannot find AGP version in build files". I'm struggling with this message and I found the empty AGP version in my project structure. I've already checked
gradle-7.3-bin
inside
C:\Users\abc.gradle\wrapper\dists' and allocated 'Gradle user home'
as 'C:\Users\abc\.gradle.
That dropdown button below the 'Android Gradle Plugin Version' has nothing and I want to find out why and how to fix it. Is this related with the AGP upgrade?

I got the same error when in Android Studio I tried to use Tools > AGP Upgrade Assistant.
For those who don't know, the Android Gradle Plugin is the dependency com.android.tools.build:gradle: specified in the project-level build.gradle (to be clear, not my module-level build.gradle).
In my case, the problem was that my project-level build.gradle file specified the version of the Android Gradle Plugin using a variable rather than hardcoding the version.
My project had the following variable in my gradle.properties and referenced it in my build.gradle file:
gradle_version=7.2.2
It referenced it in the project-level build.gradle file like this:
classpath "com.android.tools.build:gradle:$gradle_version"
To fix the problem, I changed my project-level build.gradle file from this:
classpath "com.android.tools.build:gradle:$gradle_version"
To this:
classpath 'com.android.tools.build:gradle:7.3.1'
After that change, Tools > AGP Upgrade Assistant stopped complaining "Cannot find AGP version in build files". Furthermore, I was able to use AGP Upgrade Assistant to upgrade from com.android.tools.build:gradle:7.2.2 to com.android.tools.build:gradle:7.3.1.

Unsupported method: AndroidArtifact.getBuildConfigFields()

I have just updated to Android Studio 4.0 and trying to build my project. I keep on getting the below error
Unsupported method: AndroidArtifact.getBuildConfigFields().
The version of Gradle you connect to does not support that method.
To resolve the problem you can change/upgrade the target version of Gradle you connect to.
Alternatively, you can ignore this exception and read other information from the model.
I am already using the latest version of Gradle and Gradle Plugin
Gradle version:
distributionUrl=https\://services.gradle.org/distributions/gradle-6.5-milestone-1-all.zip
Gradle plugin tools version:
classpath 'com.android.tools.build:gradle:4.1.0-alpha10'
Any solution or fix for this problem would be helpful. Thanks in advance.

Use Android studio 4.1 preview
or
classpath 'com.android.tools.build:gradle:4.0.0'

This is usually due to a mismatch between your Android Studio versions and the Android Gradle plugin.
You can find the version of Android Studio on the project selection window when you first open it (or in "Android Studio > About Android Studio" on Mac, and similar location on other platforms). For example, you might be using Android Studio 4.0.1.
You can find the Android Gradle plugin version for your project in the top-level build.gradle file.
You should find something like the following:
buildscript {
[...]
dependencies {
classpath 'com.android.tools.build:gradle:4.0.1'
[...]
}
[...]
}
You need to make sure that the two version numbers match (in this case they do).

Could not find gradle 3.1

The latest version of gradle is 3.1 enter link description here
but Android Studio is only using 2.2?
enter link description here
This seems likes a huge discrepancy. My configuration:
buildscript {
repositories {
jcenter()
mavenCentral()
maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
}
dependencies {
classpath 'com.android.tools.build:gradle:2.2'
classpath 'de.felixschulze.gradle:gradle-hockeyapp-plugin:3.2'
classpath 'com.michaelpardo:activeandroid:3.1.0-SNAPSHOT'
}
}
allprojects {
repositories {
jcenter()
}
}
When I try to find gradle 3.1, I get an error that it cannot find it. Same now with 2.2 > Could not find com.android.tools.build:gradle:2.2.
But gradle -v shows
gradle -v
------------------------------------------------------------
Gradle 2.2
how do I resolve this?

You are confusing Gradle with the Android gradle plugin, which generally matches the version of Android Studio. The latest version (at time of writing) is 2.2.2. It is generally set in your project's base build.gradle as you have shown above.
The Gradle wrapper is what you're looking for. You can change the wrapper's settings in your project's gradle/wrapper/gradle-wrapper.properties file.
Change
distributionUrl=https\://services.gradle.org/distributions/gradle-2.14.1-all.zip
to
distributionUrl=https\://services.gradle.org/distributions/gradle-3.1-all.zip
Again, this is separate from the Android gradle plugin, which simply marries Gradle with Android Studio.

Here is the Gradle Version Compatibility for Android Studio

refer to link

A problem occurred research project ': sample'.
Failed to apply plugin [id 'com.android.application']
Minimum supported Gradle version is 3.3. Current version is 3.2.1.
The current gradle configuration is also changed to 3.3. The project is running without problems, but can not use the command line (gradle and ./gradlew).
Refer to the online program:
1. Modify gradle-wrapper.properties, and Invalidate Caches / Restart ..., or do not work.
Later in the gradle forum to find a program: Thank you Henry
As new release with the fix not available yet, the former walk-around works fine.
Buildscript {
System.properties ['com.android.build.gradle.overrideVersionCheck'] = 'true'
...
}
. So mark what.
Correction statement : I later found that I installed the sdkman tool,
the tool installed 3.2.1 version, and this should be related (⊙ o ⊙)!
. At the beginning of the show gradle version, will show 3.2.1
version (I am still very depressed, change or show 3.2.1), I have
changed to the environment variable 3.3. I set the gradle environment
variable first, the following is set sdkman environment variable (this
order may also affect). So the final reason is still installed 3.2.1
version.

Android Build issue while creating a new project

I have been struggling with this gradle for the last one week. None of the earlier questions on gradle issue could solve my problem.
Things I did :
Download the latest gradle. I did it by changing the path at distribution URL in gradle-wrappper properties.
(It will download the latest one say 2.14. but, When I create a new project, It will be set to 2.10 and then back to same dirt)
Should I download the gradle for every project I create ? ... Help me fix this.
Thanks in advance :)
This is the error when I create a new project

Use the latest version of gradle with in build.gradle.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.1.2'
}
}

Don't confuse gradle and the android plugin for gradle.
1) You can define the gradle distribution used by a project in the file
gradle/wrapper/gradle-wrapper.properties
For example:
distributionUrl=http\://services.gradle.org/distributions/gradle-2.14-all.zip
Each project can use a different version. You will find the distributions file inside \user\.gradle\wrapper\dists folder.
2) Gradle is a build tool, but it requires specific plugin to work.
Android Tool Team is releasing the Android plugin for Gradle.
You can define the plugin inside the build.gradle file in the project.
For example:
classpath 'com.android.tools.build:gradle:2.1.3'
Each project (or module) can use a different version.
Also go to File > Settings > Builds,Execution,Deployment > Build Tools > Gradle
and set Use default gradle wrapper

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.

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
