未找到持久性 JPA [重复]

问：

首先，我不认为这是重复的，因为我检查了文件夹名称以及持久性名称文件

我更新了 pom 以使用 maven。

  <dependencies>
      
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
    
    <!-- JPA -->
    <dependency>
        <groupId>javax.persistence</groupId>
        <artifactId>javax.persistence-api</artifactId>
        <version>2.2</version>
    </dependency>

    <!-- Hibernate (JPA Implementation) -->
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>
        <version>5.5.6.Final</version>
        <scope>compile</scope>
    </dependency>

    <!-- Derby -->
    <dependency>
        <groupId>org.apache.derby</groupId>
        <artifactId>derby</artifactId>
        <version>10.15.2.0</version>
    </dependency>
    
  </dependencies>

我仍然没有得到未找到的持久性

请查看图片了解更多背景信息

<persistence-unit name="Memories" transaction-type="RESOURCE_LOCAL">

这是数据模型

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;

import com.fcul.memoriesdb.domain.Photograph;

import java.util.List;
 
public class PhotographDataMapper {
 
    private EntityManagerFactory entityManagerFactory;
 
    public PhotographDataMapper() {
        // Create the EntityManagerFactory
        entityManagerFactory = Persistence.createEntityManagerFactory("Memories");
