更新 android studio & gradle 插件后未配置 Kotlin

Question

这是 build.gradle 项目文件：

buildscript {
    ext.kotlin_version = '1.3.72'
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.0.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.3.3'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
plugins {
    id 'org.jetbrains.kotlin.jvm' version '1.3.72'
}
allprojects {
    repositories {
        google()
        jcenter()
    }
}
repositories {
    mavenCentral()
}
compileKotlin {
    kotlinOptions {
        jvmTarget = "1.8"
    }
}
compileTestKotlin {
    kotlinOptions {
        jvmTarget = "1.8"
    }
}
dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"
}

这是 build.gradle 应用文件：

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-kapt'

apply plugin: 'kotlin-android-extensions'
apply plugin: 'com.google.gms.google-services'

        multiDexEnabled = true
    }
    buildTypes {

        }
    }
    dataBinding { enabled = true }
}

dependencies {

}

Android gradle plugin version (4.0.1) & gradle version (6.5.1)

我也无法打开文件->设置，我点击它但没有打开任何窗口。

我试过“为项目配置 Kotlin”，它说没有可用的配置器。

我已尝试重建、清理、无效和重新启动。

我在 stackoverflow 上尝试了许多以前的解决方案，但都没有成功。

我仍然有 Kotlin 未配置的问题，非常感谢任何帮助。

Answer 1

已解决-删除C:\Users\YourUserName中的.AndroidStudio4.0目录

Android Studio 会自动创建一个新的，没有问题。

Answer 2

使用 kotlin lang 创建一个新的活动，它会自动配置 kotlin
