使用Gradle时，抽象模式类型未知

标签： java jpa gradle eclipselink

我正在学习JPA，我有一个项目，我放弃了所需的JAR并且工作正常，单元测试正在通过。

然后我决定把它作为Gradle项目，现在我有了＃34;抽象模式类型未知＆＃34;。

我的＆＃34; persistence.xml＆＃34;文件位于类路径上，因为当它没有出现错误并修复它时。

以下是working project

的项目架构的屏幕截图

尽管使用了完全相同的来源，但gradle one无法正常工作：

这是我的persistence.xml 

<persistence 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 persistence_1_0.xsd"
version="1.0">
<persistence-unit name="TP_ADW" transaction-type="RESOURCE_LOCAL">
    <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
    <exclude-unlisted-classes>false</exclude-unlisted-classes>
    <properties>
        <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" />
        <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/adw" />
        <property name="javax.persistence.jdbc.user" value="edouard" />
        <property name="javax.persistence.jdbc.password" value="monkey" />
        <property name="eclipselink.logging.level" value="FINE"/>
    </properties>
</persistence-unit>

这是一个堆栈跟踪

感谢@coladict的回答：

  

我不知道它是否与EclipseLink相同，但是在Hibernate中，如果你的persistence.xml与实体类处于不同的类路径级别（不同的jar / war），那么它有将它们全部列出，或者它们不会被检测到。

这是问题
