今天升级了一下Android Studio，同时升级了一下gradle的版本，升级之后项目运行不起来，而且Gradle报了下面的错：

然后查看了一下日志idea.log，其中的一部分日志如下：

仔细查看第一行GradleConnectionException: Could not install Gradle distribution from 'https://services.gradle.org/distributions/gradle-3.3-all.zip'.，此刻大致可以猜测出问题出在了哪里，gradle没有下载下来，这时候我们进入gradle的下载目录C:\Users\lean\.gradle\wrapper\dists可以看到3.3的包并没有下载下来，这个时候我们可以直接从网上下载相应版本的包放在对应的版本目录下然后解压出来就可以了，下载地址(http://services.gradle.org/distributions)，然后解压，解压后的目录结构如下
