Unhandled Exception Type Java

Question

I am using Sikuli with Java to create a small automation tool. I am having trouble with this Unhandled Exception error. I am trying to pass a method I created to the GUI actionPerformed method.

package mission;
import org.sikuli.script.FindFailed;
import org.sikuli.script.Pattern;
import org.sikuli.script.Screen;

import tools.ChooseMission;

public class Story {

    public static  void runStoryMissions(int chapter, int stage) throws FindFailed, InterruptedException {
        Screen screen = new Screen(); 
        ChooseMission.ChooseChapter(screen,chapter);
        ChooseMission.ChooseStage(screen, stage);
        int dailyBiometricCount = ChooseMission.dailyBiometricCount(screen); 

        Pattern start = new Pattern("img/chapters/start.png"); 
        Pattern replay = new Pattern("img/chapters/replay.png"); 
        Pattern next = new Pattern("img/chapters/next.png"); 
        Pattern mission_finish_bar = new Pattern("img/chapters/mission_finish_bar.png");


        screen.click(start); 
        System.out.println("The mission has started.");


        Thread.sleep(2000);
        while (find(screen, mission_finish_bar) == false) {

            System.out.println("Still playing the mission...");

        }
        if (screen.exists(mission_finish_bar) != null){
            System.out.println("The mission has finished.");

        }
        System.out.println("Wait for 5 Seconds");
        Thread.sleep(5000);
        System.out.println("Click repeat button");
        screen.click(replay); 

    }

Here is the code for my actionPerformed listener button:

btnStartMissions.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent arg0) {
            int chapter = Integer.parseInt(txtFldChapter.getText()); 
            int stage = Integer.parseInt(txtFldStage.getText());

            System.out.println("Chapter #: " + chapter);
            System.out.println("Stage #: " + stage);


            try {
                Story.runStoryMissions(chapter, stage);
            } catch (FindFailed e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

        }
    }

There is a error at Story. runStoryMissions(chapter,stage) it says: Unhandled Exception type FindFailed and InterruptedException

Answer 1

Okay, I found the answer to my problem if anyone is interested.

• Sikuli uses the java.awt features so scripts cannot implement and use Swing elements.
• Java AWT Robot actions cannot be called froma Java swing container.

Solution is to create a new Thread:

        new Thread(() -> {
            try {
                Story.runStoryMissions(chapter, stage);
            } catch (FindFailed | InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }).start();
