Question

我们有一个由多个JAR组成的Java EE项目，其中几个包含实体。该应用程序打包为具有以下结构的EAR：

app.ear
    lib/core.jar (containing META-INF/persistence.xml)
    lib/module1.jar (contains entities)
    lib/module2.jar (contains entities)
    ...

在persistence.xml中，我们尝试引用包含如下实体的JAR文件：

<persistence ...>
  <persistence-unit name="someName">
    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>

    <jar-file>module1.jar</jar-file>
    <jar-file>module2.jar</jar-file>

    ...
  </persistence-unit>
</persistence>

我看一下JPA 2.1 spec（也在this SO answer中引用），我的配置应该是正确的，对吧？我们的设置对应于JPA规范8.2.1.6.3中的示例2。但是，当我部署应用程序时，我收到此错误消息：

java.lang.IllegalArgumentException: File [module1.jar] referenced by given URL [file:module1.jar] does not exist

    at org.hibernate.jpa.HibernatePersistenceProvider.createEntityManagerFactory(HibernatePersistenceProvider.java:69)

我也尝试过其他路径，例如lib / module1.jar，但结果总是一样的。如果重要，我们将使用Hibernate 4.3.5.Final。是什么给了什么？

更新

显然这是Hibernate中一个古老的错误：HHH4161。任何人都有一个很好的解决方法吗？从他们的Jira来看，这不会很快得到修复。

使用<jar-file> </jar-file>在JPA persistence.xml中引用JAR文件时出错
