Ошибки конфигурации Java Mybatis Xml

Я пытался подключиться к базе данных mysql с помощью инфраструктуры Mybatis, следуя нескольким руководствам. Главный из них - http://webappdevelopmentlab.com/mybatis-tutorial-quick-start-guide/

Я пытался исправить эту проблему в течение двух дней и не могу понять, проблема ли это в моей конфигурации или синтаксисе в моем картографическом xml. База данных, которую я создал в mysql, имеет те же имена столбцов, что и атрибуты в классе java.

Ошибка говорит, что это могло быть в mapper xml, но я не вижу в этом ничего плохого.

Используется только стандартный Java-проект, а не maven.

Вот мои файлы в Структура файла проекта

mybatis-config.xml

<?xml version = "1.0" encoding = "UTF-8" ?>

Deliverable.java

public class Deliverable {

@SuppressWarnings("deprecation")
public Deliverable(){
    ID = 0;
    name = "PLACEHOLDER";
    description = "PLACEHOLDER";
    dueDate = new Date(2019,8,5);
}

public int getID() {
    return ID;

    dueDate.setDate(day);

Это ошибка, которую я получаю
