Gradle 同步失败 - Android Studio 2.3.1

Question

我的代码在更新前运行良好。但是我更新到2.3.1之后就开始报如下错误，

    Error:org.gradle.api.internal.tasks.DefaultTaskInputs$TaskInputUnionFileCollection cannot be cast to org.gradle.api.internal.file.collections.DefaultConfigurableFileCollection
Possible causes for this unexpected error include:<ul><li>Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)
<a href="syncProject">Re-download dependencies and sync project (requires network)</a></li><li>The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.
<a href="stopGradleDaemons">Stop Gradle build processes (requires restart)</a></li><li>Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.</li></ul>In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.

请帮忙。

终于找到了解决办法。

指定 gradle 版本。您可以在 Android Studio 的 File > Project Structure > Project 菜单或顶级 build.gradle 文件中为 Gradle 版本指定 Android 插件。该插件版本适用于该 Android Studio 项目中构建的所有模块。以下示例从 build.gradle 文件将 Gradle 的 Android 插件设置为 2.3.1 版本：

 buildscript {
  ...
  dependencies {
    classpath 'com.android.tools.build:gradle:2.3.1'
  }
}
