Android studio 3.2.1 ArtifactResolveException：无法解析配置“：类路径”的所有工件

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
}

Update

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

Answer 1

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 continue sally.

As you can see the image

Answer 2

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.

Answer 3

In my case, I have added a dependency which is not available in any of the cloud repositpories. On removing dependency ,it started working

Answer 4

Check the below points.

1. Internet connectivity issue.
2. Toggle Offline Mode.

Answer 5

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

Answer 6

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.

Answer 7

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.

Answer 8

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.

Answer 9

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.

Answer 10

将项目升级到 androidx 更改编译到实现 将 v4 或 v7 更改为 androidx 依赖项

Answer 11

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.

Answer 12

只是你必须打开切换按钮，进入窗口右侧的成绩菜单......所以你要进入在线模式......你必须有互联网连接才能......建立成绩......否则它会再次显示给你相同的错误或其他类型的错误...

Answer 13

对我来说，问题是需要更改组织的 Artifactory 密码才能使用新凭据更新 Gradle。

Answer 14

This Works 100%

turn off the Toggle Offline Mode .

Check the image below

Answer 15

您可能添加了存储库中不可用的依赖项

Answer 16

This error may arrises due to "android:exported="false"". please make sure when to use "android:exported="true/false"".

Answer 17

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

Answer 18

actually i ran into this problem. in my opinion error is due to version of libraries in file gradle. you should change versions for this to work. this way was ok for me...

Answer 19

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

Answer 20

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

Answer 21

In my case I added maven repository in both repository section, so this issue occurs, So I removed this line from above repotories section inside buildscript for reference visit this answer https://stackoverflow.com/a/75005827/12748481

Answer 22

我也遇到了同样的错误，因为当我更新我的 Android 工作室时，即使使用快速的互联网网络也无法启动一个新项目，但今天我发现了一个解决方案，只需点击你的事件日志并更新任何显示的建议插件重建你的项目，然后你的项目运行良好，它对我有用，相信它也对你有用。
