Answer 1

Follow the steps in the 3.0.0 plugin migration guide

Update gradle version

The new Android plugin requires Gradle version 4.1-milestone-1 or higher. If you're opening an existing project using Android Studio 3.0 Preview 5 or later, follow the prompts to automatically update an existing project to the compatible version of Gradle.

To update Gradle manually, update the URL in gradle-wrapper.properties as follows:

distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-milestone-1-all.zip

and

Apply the plugin

If you're opening an existing project using Android Studio 3.0 Preview 5 or later, follow the prompts to automatically update your project to the latest version of the Android plugin. To manually update your project, include the maven repo and change the plugin version in your project-level build.gradle file as follows:

buildscript {
  repositories {
    ...
    // You need to add the following repository to download the
    // new plugin.
    jcenter()
    google()
  }

  dependencies {

    classpath 'com.android.tools.build:gradle:3.2.1'  //Minimum supported Gradle version is 4.6
  } 
}

Answer 2

You try :

buildscript {
    repositories {
        ...
        // You need to add the following repository to download the
        // new plugin.
        google()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
    }
}

Answer 3

If you're in Android Studio 3.1 or higher, you're likely encounter such type of issue prompting by a Build window.

Simply click on the Add Google Maven repository and sync project option at right side and initiate another gradle sync.

It'll make the necessary changes in both gradle-wrapper.properties as well as build.gradle files.

Answer 4

Update gradle plugin : in gradle.properties file add this line distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip

then apply ther plugin in build.gradle file :

buildscript {
repositories {
    ...
    // You need to add the following repository to download the
    // new plugin.
    google()
}

dependencies {
    classpath 'com.android.tools.build:gradle:3.0.1'
}

}

Answer 5

the distributionUrl property inside gradle-wrapper.properties should be:

distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip

that works for me

Answer 6

1. open the file path(just as the log said): file:/C:/Users/dmin/Documents/android-studio/gradle/m2repository/com/android/tools/build/gradle/

2. found this file

3. just change classpath 'com.android.tools.build.gradle:3.0.0-alpha7' to classpath 'com.android.tools.build.gradle:* * * ' ; * * * is the exist gradle file;

   this problem is because of gradle file do not found
