Java 带SQLite的JPA-持久性异常

我正在尝试将jpa与sqlite一起使用。当我尝试启动EntityManager时，我得到：

Exception in thread "main" javax.persistence.PersistenceException: No persistence providers available for "CustomerLibraryPU" after trying the following discovered implementations: org.eclipse.persistence.jpa.PersistenceProvider

我是jpa的新手，所以如果有人能告诉我我做错了什么，那就太好了。我一直在广泛地寻找，试图找到我的错误，但没有结果

下面是我的persistence.xml文件：

<?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="socialEngineeringToolPU" transaction-type="RESOURCE_LOCAL">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<class>socialengineeringtool.models.Employee</class>
<class>socialengineeringtool.models.Business</class>
<class>socialengineeringtool.models.Department</class>
<properties>
  <property name="javax.persistence.jdbc.url" value="jdbc:sqlite:&lt;FILE&gt;"/>
  <property name="javax.persistence.jdbc.user" value="businessApp"/>
  <property name="javax.persistence.jdbc.driver" value="org.sqlite.JDBC"/>
  <property name="javax.persistence.jdbc.password" value="testPass"/>
  <property name="javax.persistence.schema-generation.database.action" value="create"/>
</properties>
</persistence-unit>
</persistence>

org.eclipse.persistence.jpa.PersistenceProvider
socialengineeringtool.models.Employee
socialengineeringtool.models.Business
socialengineeringtool.models.Department

看看这里：我从未配置过SQLite，但我猜您的

persistence.xml

是错误的。消息是EclipseLink不在类路径中（或者EclipseLink已经看到您正在使用SQLite，并且不支持它？）
