November 29, 2021
How to fix Gradle project sync failed. Basic functionality (e.g. editing, debugging) will not work properly:
This is a common issue in Android Studio. If your Gradle sync failed, you might get an error with a message that describes your issue. This error is easy to fix if the reason is mentioned.
But, if you are getting the following error without any specific reason, it becomes harder to solve.

It shows three buttons Try Again, Open Build View and Show log in Explorer.
- If you click on the Try Again button, it will try to sync the project again and it will fail.
- If you click on the Open Build View button, it will open the Build view in Android studio as like below:
If you see any error logs, you can fix it. But in my case, there is no error logs except the time-stamps.
The third button can help you in some cases. Don’t use Android Studio after the sync failed and click on that button, Show Log in Explorer.
It will open a folder containing idea.log file. Android studio or IntelliJ Idea logs its exceptions and other log messages in this file. You can move to the bottom of the file to get the error. You will get the exception stack-trace with details.
In my case it was:
