通过使用createEntityManagerFactory实现javax.persistence.PersistenceException

我下面的代码在我的Windows上运行，但在我的Linux Mint上不运行。A添加了所有相关的库。 我在createEntityManagerFactory行中遇到此异常：

javax.persistence.PersistenceException: Explicit persistence provider error(s) occurred for "JPA_probaPU" after trying the following discovered implementations: org.eclipse.persistence.jpa.PersistenceProvider from provider: org.eclipse.persistence.jpa.PersistenceProvider

我的java文件：

package jpa_proba;

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
import org.eclipse.persistence.exceptions.EntityManagerSetupException;

public class JPA_proba {

public static void main(String[] args) {
    try{
    EntityManagerFactory emf = Persistence.createEntityManagerFactory("JPA_probaPU");
    EntityManager em = emf.createEntityManager();
    em.getTransaction().begin();
    //Integer id, String isbn, String szerzo, String cim, String mufaj, int ar, int elerheto
    Konyv k = new  Konyv(null, "654654444444", "Kiss Béla", "Hogyan ne csináljunk semmit?", "dráma", 500, 1);
    em.persist(k);
    em.getTransaction().commit();
    }
    catch(Exception ex){
    System.out.println(ex);
    }
  }

}

My persistence.xml：

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
  <persistence-unit name="JPA_probaPU" transaction-type="RESOURCE_LOCAL">
    <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
    <class>jpa_proba.Konyv</class>
    <properties>
      <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/helix1?zeroDateTimeBehavior=convertToNull"/>
      <property name="javax.persistence.jdbc.user" value="root"/>
      <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver"/>
      <property name="javax.persistence.jdbc.password" value="123456"/>
    </properties>
  </persistence-unit>
</persistence>

您将获得

内部异常：java.lang.CompatibleClassChangeError:实现类

当同一类/jar有多个版本时，可能会发生这种情况
