Android studio 3.2.1 ArtifactResolveException: Could not resolve all artifacts for configuration ':classpath'

After I update Android Studio to 3.2.1 and gradle version in my project I am getting following build error.

I have already checked lots of questions related this question but no luck.

Project dependency Build.gradle

buildscript {

    repositories {
        google()
        mavenCentral()
        maven { url 'https://maven.google.com' }
        gradlePluginPortal()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        maven { url "https://jitpack.io" }
        jcenter ()

    }
}

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

Error

In my case, I have noticed there are Test Dependencies. Upon removing these dependencies, it started working/downloading again.

these are under dependencies on build.gradle scripts

i.e.

//    testImplementation(libs.junit)

//    androidTestImplementation(libs.androidx.junit)

//    androidTestImplementation(libs.androidx.espresso.core)

In my case i have miss typed the name of the group from "android" to "ambroid". Just check the spelling also resolved the problem.

android-gms-playservice-maps = {group = "com.google.android.gms", name="play-services-maps", version.ref = "maps"}

In my case I had conflicting credentials for the same maven repository under different gradle files. It worked once the conflicts were resolved.

If you are running into this problem and the above answers have not being solved yet you should check your invalid dependencies.

In my case, All of the above answers didn't solve it. I dug into the details in this error and found that there were some messages that had retrofit2 in them. So I temporarily removed retrofit2 dependencies in my module level's build.gradle.kt

build.gradle.kt

// I commented out two dependencies.
//    implementation(libs.retrofit)
//    implementation(libs.converter.gson)

After that, my project worked.

In my case to make it work I removed the .gradle and .idea folders and then make an invalidate & restart. I hope I can help someone!

i faced this issue after adding

implementation("com.squareup.okhttp3:okhttp:3.1.0")

i removed it and issue resolved.

moral of the story:
remove older implementations if (another resource already has newer classes)
also check internet connection.

Mostly, there is always a dependency that you might have added that doesn't exit, so you have to find and delete it. This worked for me.

Try to Toggle Offline Mode, if not worked check your flipper version if it is old try to update it(worked for me). Upgrading flipper version in gradle.properties

From

FLIPPER_VERSION=0.39.0

FLIPPER_VERSION=0.99.0

Deleting my .gradle file ("C:\Users<userName>.gradle") and going to the device manager and running "Cold Boot Now" fixed this problem for me

Just turn off the Toggle Offline Mode .

On the top right side of the Window .

Click on Gradle 2nd number option(just near of Setting option) click on it then you will be able to do work continuously.

As you can see the image

In my case none of the above helped. I had to upgrade my FLIPPER_VERSION in my gradle.properties file. You can find the latest FLIPPER_VERSION here: https://github.com/facebook/flipper/releases

My problem was because a version was wrong in the dependencies in build.gradle (app). If you have internet, it might be because of this, so try finding other warnings that might indicate a wrong dependency.

This problem occurs when your android studio is not getting internet connection. You fix the internet, the problem fixes by itself. To confirm the internet issue of the android studio you can attempt to login, update, connecting to firebase, etc all will fail.

I had this problem also. Tried all the suggestions, but didnt help. The problem was in offline/online mode as other stated but you have to also check the compiler settings. Make sure there is no --offline flag

Preferences -> Build, Execution, Deployment -> Compiler

( Menubar 'File' button, 'Settings' menu option, 'Build, Execution, Deployment' menu twisty, 'Compiler' submenu )

On Command-line Options: --stacktrace

not

--offline --stacktrace

Opening the "Gradle" side panel, and toggling the "online/offline" button to "online" worked for me as well.

Previous failed solution: I searched on Gradle's website for a manual download of version 3.6.3, but there wasn't one. That number is the same version, however, of Android Studio being used.

If you have updated Gradle then most likely you will get this error because Gradle will be offline by default after updating.

Solution:

In right hand side top corner click Gradle (Gradle panel or Gradle window opens). Connect Gradle to the internet by clicking the icon at the top of Gradle panel or window.

In The Right Side of the Android Studio, You can See Gradle option just click it and you will see a screen which is given below.

Gradle can be offline. If offline, you should do it online.

This problem appeared on OS X. After disabling web filtering application (some Google IPs were blocked) it disappeared. After syncing with gradle all files have been downloaded.

Also you may set a checkbox like in https://discuss.gradle.org/t/android-studio-could-not-get-resource-https-dl-google-com-dl-android-maven2-com-android-tools-build-gradle-3-1-0-gradle-3-1-0-pom/26734:

Settings -> Build … -> Gradle -> Android Studio -> Enable embedded maven repository.
