Repair Gradle Installation
This usually happens when something goes wrong in Android Studio’s first launch (eg. system crash, connection loss or whatever).
To resolve this issue close Android Studio and delete the following directory’s content, necessary files will be downloaded on IDE’s next launch.
macOS: ~/.gradle/wrapper/dists
Linux: ~/.gradle/wrapper/dists
Windows: C:\Users\your-username\.gradle\wrapper\dists
While downloading Gradle manually works, I recommend letting Android Studio itself to do it.
