Question

我的NetBeans-Maven项目出了问题。如果我将另一个持久性单元添加到具有相同实体的同一个persistence.xml中，我会得到一些我不理解的异常。

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
  <persistence-unit name="com.xxx.plugin.connector_xxxAuthServices_war_firstPU" transaction-type="RESOURCE_LOCAL">
    <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
    <class>com.xxx.plugin.entities.Businesspartner</class>
    <exclude-unlisted-classes>false</exclude-unlisted-classes>
    <shared-cache-mode>NONE</shared-cache-mode>
    <validation-mode>NONE</validation-mode>
    <properties>
      <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/db_first?zeroDateTimeBehavior=convertToNull"/>
      <property name="javax.persistence.jdbc.password" value="xxx"/>
      <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver"/>
      <property name="javax.persistence.jdbc.user" value="root"/>
    </properties>
  </persistence-unit>

  <!--  
  <persistence-unit name="com.xxx.plugin.connector_xxxAuthServices_war_secondPU" transaction-type="RESOURCE_LOCAL">
    <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
    <class>com.xxx.plugin.entities.Businesspartner</class>
    <exclude-unlisted-classes>false</exclude-unlisted-classes>
    <shared-cache-mode>NONE</shared-cache-mode>
    <validation-mode>NONE</validation-mode>
    <properties>
      <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/db_second?zeroDateTimeBehavior=convertToNull"/>
      <property name="javax.persistence.jdbc.password" value="xxx"/>
      <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver"/>
      <property name="javax.persistence.jdbc.user" value="root"/>
    </properties>
  </persistence-unit>
  -->
</persistence>

如果我取消注释第二个PU，我会得到一些例外：

could not parse error message:   symbol:   class Businesspartner
location: package com.xxx.plugin.entities

MaterialsLoginRESTfulWSTest是一个jUnit-Test，第9行是“import com.xxx.plugin.entities.Businesspartner”。

我在我的智慧结束。是否有人有答案帮我解决问题......

忘记发布我的修复/错误。我在Maven-Rep上有一个旧的或不匹配的版本。
