Android Gradle插件仅支持Kotlin Gradle插件版本

我正在尝试运行我的项目，它运行没有任何问题，但在我更新Android Studio之后。。我有一个错误，我不知道在升级之前我使用了哪个android studio版本来降级到它

Android Gradle插件仅支持Kotlin Gradle插件版本1.3.0及更高版本。 以下依赖项不满足所需版本： 项目：assets\u audio\u player'->org.jetbrains.kotlin:kotlin gradle插件：1.2.71

谢谢，

我也遇到了同样的问题，下面的答案为我解决了这个问题：

我在添加flatter谷歌地图插件时遇到了类似的错误问题。我将android/build.gradle中的gradle版本从

com.android.tools.build:gradle:3.3.1

更改为

com.android.tools.build:gradle:3.2.1

，将Kotlin版本从

1.2.71

请参阅下面的代码

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"
    }
}

这实际上是两败俱伤。问题是你使用的是3.3.1版或更高版本的Android Gradle插件，该插件强制使用Kotlin 1.3.0或更高版本。因此，您只有一个解决方案—将Android Gradle插件降级为3.2.1版。 ...

转到外部库/flatter插件/assets\u audio\u player/android/build.gradle并将ext.kotlin\u版本更改为最新版本
