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

Question

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
}

I just followed @CoolMind answer it solve the gradle issue, but there is another issue comes which is This

And I followed those answers which is given in this question but not solve my problem

check your connectivity while building gradle for project, also make sure you are not behind any firewall. — karan, Dec 26 '18 at 12:42
if you're in a sanctioned country use vpn/proxy that covers the whole PC restart Android Studio and make sure google() is first option and mavenCentral() is second — Alireza Jamali, Dec 30 '22 at 15:26

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

It is hard to tell whether you are in 'offline' or not offline mode. I think having the little interrupted horizontal bar means offline. Having a gray box around the bar means not-offline -- ie online. Having the tool tip just say toggle offline doesn't help. Seeing it in a dark theme is hard too. – Ribo May 20 '20 at 22:04

Doesn't work for me. Toggling offline mode makes no difference whatsoever. I think you should take out the 100% solution part! – gignu May 16 '22 at 17:39

@Vikassingh no, I get exactly the same error message as in the title of this question. The solution in my case was to upgrade my FLIPPER_VERSION in my gradle.properties file which was outdated. Once I did that, the error was gone and the build succeeded. If you're interested and want to reproduce it, change your FLIPPER_VERSION to 0.52.1 and you should get the same build error as in the title of this question. – gignu May 17 '22 at 15:59

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.

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.

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.

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.

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.

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.

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.

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

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

To

FLIPPER_VERSION=0.99.0

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.
