Gradle's dependency cache may be corrupt解决方法

问题描述：

  Error:Unable to find method 'com.google.common.cache.CacheBuilder.build(Lcom/google/common/cache/CacheLoader;)Lcom/google/common/cache/LoadingCache;'.
  Possible causes for this unexpected error include:
  Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)
  Re-download dependencies and sync project (requires network)
  The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.
  Stop Gradle build processes (requires restart)
  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.

解决方法：

1.Delete the .gradle directories both in your home directory and at the top level of your project.
   Gradle's cache directoires aren't affected by the "Clear caches and restart" option.
   就是删除下面的文件夹：自己目录和项目目录：

    
2.如果上面还没有解决，就下边：
 gradle-wrapper.properties里修改了gradle的版本，与之前没有报错的gradle版本一致。就可以了
 我是改为：
  http\://services.gradle.org/distributions/gradle-2.10-all.zip
