Вот основной

пакет HMS; 

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception{
        Parent root = FXMLLoader.load(getClass().getResource("AdminDashboard.fxml"));
        primaryStage.setTitle("Login");
        primaryStage.setScene(new Scene(root));
        primaryStage.show();
    }


    public static void main(String[] args) {
        launch(args);
    }
}

Я пытаюсь использовать кнопку выхода из системы (Logout_adPan). Я добавил все ссылки, и это было построено с использованием построителя сцен. Я не знаю, что я делаю не так

вы пытаетесь сравнить два объекта, используя символ ==, в то время как вы должны сделать это, используя метод equals(), который вернет истину, если они равны, в противном случае он вернет ложь.
Не забудьте привести mouseEvent.getSource() к Button
, попробуйте это: 

 if(((Button)mouseEvent.getSource()).equals(Doc_adPan))
{

}
else if(((Button)mouseEvent.getSource()).equals(Lab_adPan))
{

}
else if(((Button)mouseEvent.getSource()).equals(Logout_adPan))
{
    loadStage("Login.fxml");
}
else if(((Button)mouseEvent.getSource()).equals(Staff_adPan))
{

}
else if(((Button)mouseEvent.getSource()).equals(Settings_adPan))
{

}
else if(((Button)mouseEvent.getSource()).equals(Pharma_adPan))
{

}
else if(((Button)mouseEvent.getSource()).equals(Finance_adPan))
{

}
else if(((Button)mouseEvent.getSource()).equals(Wards_adPan))
{

}

и используйте только onAction="#handlebuttonclicks", а не onMouseClicked.

и удалить onMouseClicked="#handlebuttonclicks" из AnchorPane
