ERROR: Could not find org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.3.31

Question

我想更新 Android Gradle 插件，但我收到此错误：

ERROR: Could not find org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.3.31.

这些是我为更新 Android Gradle 插件（build.gradle 文件）添加的行：

buildscript {
    repositories {
        // Gradle 4.1 and higher include support for Google's Maven repo using
        // the google() method. And you need to include this repo to download
        // Android Gradle plugin 3.0.0 or higher.
        google()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.1'
    }
}

Answer 1

您缺少一些存储库 (jcenter) 和一些依赖项 (kotlin-gradle-plugin)。这就是找不到 Kotlin 的原因。

您的 build.gradle(Project:android) 文件应如下所示：

buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:3.4.1"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.31"
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

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