AWT Robot - only taking screenshot of current program on MacOS

Question

I'm creating a simple test program to take screenshots of the entire screen, after some research, I created the following code:

public class PrintScreenCatcher {

    public String capture(){
        try {
            Rectangle rectangle = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize());
            Robot robot = new Robot();
            BufferedImage screenShot = robot.createScreenCapture(rectangle);
            File file=createTempFilePath();
            ImageIO.write(screenShot, "jpg", file);
            return file.getAbsolutePath();
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }

    private File createTempFilePath() throws IOException {
        DateTimeFormatter formatter=DateTimeFormatter.ofPattern("yyyyMMddHHmmssS");
        return File.createTempFile("screen-"+LocalDateTime.now().format(formatter),".jpg");
    }
}

After run this program, I was expecting a image with my entire screen (MacOS menu, Intellij, etc):

Instead I got a image only containing my desktop's background:

I think robot is trying to take a screenshot only of my program. What should I do to take a screenshot of the opened screens?

Answer 1

The problem was MacOS permission. According with this answer, the program needs permission to record the screen. I simply added the access to IntelliJ in System Preferences -> Security and Privacy -> Privacy -> Screen Recording and it worked.
