Gradle's dependency cache may be corrupt

今天安装的时候遇到了这个问题

Error:Failed to open zip file. 
Gradle’s dependency cache may be corrupt (this sometimes occurs after a network connection timeout.) 
Re-download dependencies and sync project (requires network)

我出这个问题是因为下载的gradle损坏了  所以把下载的gradle压缩包删除 重启android studio 重新下载就好了
