Я очень новичок в JPA, и этот проект не мой.Я вижу, что в каталоге ./test есть несколько тестовых классов.Когда я пытаюсь запустить mvn clean package, сборка действительно завершается неудачно для тестов: у меня нет базы данных mysql, используемой тестовыми классами.Я нашел класс CreateSchema в тестовом пакете, но если я его запустил, БД не создается.Я даже пытался создать базу данных вручную, в этом случае сборка выводит ошибки об отсутствии таблиц mysql.
Это класс
package com.myproject.test;
import javax.persistence.Persistence;
import org.apache.log4j.Logger;
public class CreateSchema {
public static void main(String[] args) {
Persistence.generateSchema("MySchema", null);
}
}
Когда я запускаю его, он ничего не печатает.
Чего мне не хватает?
Это мой пом
