Import statement currently unsupported

Hello, I am trying to use Java Robot Class inside a Matlab Function Block in Simulink to simulate key-press and key-release. But I keep getting an error while running the simulink model: "Import statements are currently unsupported." My code looks something like this:

function y = fcn(u)
import java.awt.*;
import java.awt.event.*;
rob=Robot;
rob.keyPress(KeyEvent.VK_A)
rob.keyRelease(KeyEvent.VK_A)
y = [0 0];

If I simply write the above as a function in matlab or as a script, it works fine. I get the error only when trying to do it with the simulink block. Is there any work-around to avoid this problem? Or any fixes? I am using Matlab version 2017a.

Thanks in advance! -SD

If you're using this block for simulation only, you can use coder.extrinsic to get around this. There's a discussion on this here.

Thank you very much! That works!

Hello, could you show the code of the running program? Because I have the same problem but still have an error. Is that correct?

    coder.extrinsic('import');
