How do I run .jar file from Intellij IDE, built by Maven?

Question

In IntelliJ I created Maven run configuration, that looks like this:

When I run it, I get .jar file:

And when I run it, I get this message:

"C:\Program Files (x86)\Java\jdk1.8.0_251\bin\java.exe" -Dfile.encoding=windows-1250 -jar D:\Projekty\Programowanie\Portfolio\java-studying\MavenHelloWorld\target\MavenHelloWorld-1.0-SNAPSHOT.jar
no main manifest attribute, in D:\Projekty\Programowanie\Portfolio\java-studying\MavenHelloWorld\target\MavenHelloWorld-1.0-SNAPSHOT.jar

How do I run this .jar file from intelliJ?

You don't need to compile into a jar file, there's a terminal in IntelliJ to display println, just press the green start button in App.

In the future, follow these steps to create manifest and use Build>Build Artifacts>name.jar>Build to create a runnable jar file:
