尝试通过转到文件">使高速缓存无效/重新启动">使无效并重新启动"来清除高速缓存，但无济于事，因为错误仍然存​​在.

Tried clearing the cache by going to File > Invalidate Cache/Restart > Invalidate and Restart, but to no avail, as the error persists.

推荐答案

另一个可能的原因是:未为构建脚本设置Google的maven存储库.

Another possible reason is: Google's maven repository is not set for the build script.

打开项目的主版本.gradle添加此行:

Open your project's main build.gradle add this line:

buildscript {
    repositories {
        google()  <-- this
        // Be also sure that google() is before jcenter()
    }
}

否则，它可能无法下载Android Studio Gradle插件3.0+.它不在jCenter中分发，而是在Google的maven存储库中分发.

Without this, it may not be able to download the Android Studio Gradle plugin 3.0+. It's not distributed in jCenter but in the Google's maven repository.
