How to fix java.lang.NoClassDefFoundError: com/google/inject/AbstractModule in jFairy

Question

I have built jFairy project from git repository ([1]: https://github.com/Devskiller/jfairy.git) using mvnw install command. then I have imported compiled jar file to my project.

package userdao;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.SQLException;
import java.sql.ResultSet;
import com.devskiller.jfairy.Fairy;
import com.devskiller.jfairy.producer.person.Person;
import userdao.User;
/**
 *
 * @author loveu
 */
public class UserDao {

    /**
     * @param args the command line arguments
     * @throws java.lang.ClassNotFoundException
     * @throws java.sql.SQLException
     */
    public static void main(String[] args) throws ClassNotFoundException, SQLException {
        UserDao dao = new UserDao();
        User user = new User();
        Fairy fairy = Fairy.create();
        Person person = fairy.person();
        user.setId(person.getFullName());
        user.setName(person.getFirstName());
        user.setPassword(person.getEmail());
        dao.add(user);
        System.out.println(user.getId() + "successfuly");
        User  user2 = dao.get(user.getId());
        System.out.println(user2.getName());
        System.out.println(user2.getPassword());       

        // TODO code application logic here
    }

but while compiling, currently I have got that error

You can find information about required libraries inside pom.xml, it is much easier to use tools like Apache Maven to build java applications.
