Delete .gradle folder(root directory) and build folder(project directory) and then invalidate caches/restart android studio, run your project again hopefully it will work. It might take some time for the background tasks. In some countries, you may need to turn on the VPN to download.

I had the same issue yesterday. After opening the "Android SDK Manager", updating all packages and restarting Android Studio, the project compiled again.

I ran into the same issue, but then did the following, and my issue was resolved:

• updated Gradle
• installed the latest version of Android studio (mine was out of date)

And that solved my problem.

Note: It also helped me to click on the event log, because it has more detailed info about errors. https://developer.android.com/studio/releases/gradle-plugin#updating-plugin also has great info.
