Which command is used with gradle to run/debug groovy main class?

I created a run configuration for a main method in a gradle/groovy project.

I wonder how to the the command line executed to run thes main method. I notice that groovy/gradle main methods do not display this information and the run panel does not look exactly like described in the IDE help - there are less buttons.

The (only) class that contains the main method:

import org.fusesource.jansi.AnsiConsole

import static org.fusesource.jansi.Ansi.ansi
import static org.fusesource.jansi.Ansi.Color.*

class CliTest2 {
    static main(args) {
        AnsiConsole.systemInstall();
        println ansi().eraseScreen().fg(RED).a("Hello").fg(GREEN).a(" World").reset()
    }
}

When running this configuration, I get an output like:

23:55:04: Executing task 'CliTest2.main()'...

> Task :compileJava NO-SOURCE
> Task :compileGroovy
> Task :processResources NO-SOURCE
> Task :classes

> Task :CliTest2.main()
Hello World

What does "Task :CliTest.main()" mean? How can I reproduce it on a terminal? And does the run panel appear with less UI elements?

For example, when running the same Hello World as groovy script, the run behaves as expected. Sample code:

import org.fusesource.jansi.AnsiConsole

import static org.fusesource.jansi.Ansi.ansi
import static org.fusesource.jansi.Ansi.Color.*

AnsiConsole.systemInstall();
println ansi().eraseScreen().fg(RED).a("Hello").fg(GREEN).a(" World").reset()

Then the command line is printed as expected and the run panel looks like described in the IDE -help.

C:\Users\x7ws\.jdks\adopt-openjdk-15.0.2\bin\java.exe -Dgroovy.home=... C:\Users\...\src\main\groovy\AnsiTest.groovy
Hello World

Process finished with exit code 0

Why is the "gradle/groovy run" different thant other "run"?
