As @tech_android already posted in this comment, to solve that problem permanently, go to Module Settings > SDK Location > Use embedded JDK.

This will remove dependency on the external Java installation by using the embedded JDK.

I always spend an hour to resolve such a stupid problem instead of looking for the right answer on SO. Thanks! – Artiom Apr 04 '18 at 13:55

You can find the above window by clicking **File** > **Project Structure**. – ban-geoengineering Jun 23 '18 at 21:33

This is a bug of JDK old versions i guess. Go to the project structure and change your project to latest JDK like 1.80_72 or later versions.

Hopefully it will fix your problem.

It's resolved my issue when I used embedded JDK(recommended) option

Do this:

Project Structure -> SDK Location -> Select "Use embedded JDK(recommended)"

1) Update to the latest JDK Version, in my case jdk1.8.0_162

2) In your Android Studio select File-> Project Structure -> SDK Location -> JDK Location, write the directory C:\Program Files\Java\jdk1.8.0_162

3) Restart Android Studio

Problem Solved

Android Studio: 3.5.3
gradle plugin: 3.5.3
gradle: 5.4.1
platform: Mac OS Mojave 10.14.6 (18G103)

I had done this:Project Structure -> SDK Location -> Select "Use embedded JDK(recommended)" but it still not working.

when I read this article,

you can add a property at gradle.properies:

org.gradle.java.home=(path to JDK home)

it works!
