Q:

Where to see the output of Hello World built by Gradle on IntelliJ?

Where can I see the output of Hello World built by Gradle on IntelliJ?
It should print out 'Hello World'.

A:

What you did is you built the project, i. e. you compiled the source code. Instead of building your project, you may want to click the Play button next to public class HelloWorld and then "Run HelloWorld.main()". This will cause IntelliJ to not only compile your source code but also to run the program
