我该如何解决这个问题？

Answer 1

您更新到 Android Studio 3.0 Canary 1 了吗？

如果是这样，我也有同样的问题。他们将一些东西移到了新的存储库：https://maven.google.com

所以我不得不在我的 build.gradle 文件中添加以下代码

repositories {
  maven {
   url "https://maven.google.com"
  }
}

另外，还在 gradle 中，我不得不更新以下依赖项：

dependencies {
  classpath 'com.android.tools.build:gradle:3.0.0-alpha1'
}

最后，gradle-wrapper 也需要更新：

distributionUrl=https\://services.gradle.org/distributions/gradle-4.0-milestone-1-all.zip

希望对你有帮助

Answer 2

我已经通过删除 Android Studio 根目录中的文件夹“gradle”，在 Android Studio 中运行 File -> Invalidate Caches / Restart 然后将文件夹“gradle”复制到 Android Studio 的根目录来解决这个问题Android Studio 版本。然后再次重启 Android Studio。

我并不是说这是解决此问题的正确方法，但它对我有用 - Android Studio alpha 和 beta 不是稳定版本。
