The Android Gradle plugin supports only Kotlin Gradle plugin version

Question

I'm trying to run my project, it was running without any problem, but after I update Android Studio .. I've error and I didn't know which android studio version I was used before update to downgrade to it.

The Android Gradle plugin supports only Kotlin Gradle plugin version 1.3.0 and higher. The following dependencies do not satisfy the required version: project ':assets_audio_player' -> org.jetbrains.kotlin:kotlin-gradle-plugin:1.2.71

android/app/build.gradle

buildscript {
    repositories {
        // ...
        maven { url 'https://plugins.gradle.org/m2/' } // Gradle Plugin Portal
    }
    dependencies {
        // ...
        // OneSignal-Gradle-Plugin
        classpath 'gradle.plugin.com.onesignal:onesignal-gradle-plugin:[0.10.2, 0.99.99]'
    }
}
apply plugin: 'com.onesignal.androidsdk.onesignal-gradle-plugin'

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

apply plugin: 'com.android.application'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
    keystoreProperties.load(new FileInputStream(keystorePropertiesFile))

}

android/build.gradle

buildscript {
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.1'

    }
}

allprojects {
    repositories {
        google()
        jcenter()

    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')

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

I encountered a similar error issue when I added Flutter Google maps plugin . I changed the gradle version in android/build.gradle to com.android.tools.build:gradle:3.3.1 from com.android.tools.build:gradle:3.2.1 and the Kotlin version to 1.3.21 from 1.2.71

See code below

buildscript {
    ext.kotlin_version = '1.3.21'
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

This actually killed two birds

Answer 2

The problem is you are using version 3.3.1 or the higher version of the Android Gradle plugin, which enforces to have Kotlin 1.3.0 or above. so you only have 1 solution - downgrade the Android Gradle plugin to version 3.2.1 . ... 😍✔💌🤞👍

Answer 3

转到 External Libraries / Flutter Plugins / assets_audio_player / android / build.gradle 并将 ext.kotlin_version 更改为 LATEST_VERSION。
