android - 错误 :Could not find com. android.tools.build :gradle:3. 0.0-beta2

Question

我在编译新的 gradle 时遇到问题，如下所示:

Error:Could not find com.android.tools.build:gradle:3.0.0-beta2. Searched in the following locations: file:/C:/Program Files/Android/android-studio-preview/gradle/m2repository/com/android/tools/build/gradle/3.0.0-beta2/gradle-3.0.0-beta2.pom file:/C:/Program Files/Android/android-studio-preview/gradle/m2repository/com/android/tools/build/gradle/3.0.0-beta2/gradle-3.0.0-beta2.jar https://jcenter.bintray.com/com/android/tools/build/gradle/3.0.0-beta2/gradle-3.0.0-beta2.pom https://jcenter.bintray.com/com/android/tools/build/gradle/3.0.0-beta2/gradle-3.0.0-beta2.jar Required by: project : Open File

这是我的gradle:

buildscript {
ext.kotlin_version = '1.1.4-2'
repositories {
    jcenter()
}
dependencies {
    classpath "com.android.tools.build:gradle:3.0.0-beta2"
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}

Answer 1

你必须添加 gradle maven 仓库:

 maven { url 'https://maven.google.com' }

类似于:

buildscript {
    //..
    repositories {
        jcenter()
        maven { url 'https://maven.google.com' }
    }
    //..
}

如果您使用的是 Android Studio 3.x 和 gradle v.4，您还可以使用 google() 快捷方式

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

    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0-beta-2'
    }
}
