Question

我在JDK 1.7u52上运行的Netbeans 8.2中有一个Java EE 6项目，当我在IDE中编译并启动它时运行正常。但是，当我清理并构建项目时，我收到以下错误：

An annotation processor threw an uncaught exception.
Consult the following stack trace for details.
java.lang.RuntimeException: javax.annotation.processing.FilerException: Attempt to recreate a file for type ch.djan.lee.compute.entity.SpaceLog_
    at org.eclipse.persistence.internal.jpa.modelgen.CanonicalModelProcessor.process(CanonicalModelProcessor.java:407)

    at com.sun.tools.javac.main.JavaCompiler.processAnnotations(JavaCompiler.java:981)

注意：我正在研究Criteria和eclipsLink 2.4

Answer 1

解决方案是更新你的persistence.xml文件，如下所示：

<persistence-unit name="first_PU">
   <properties>
    <property name="eclipselink.canonicalmodel.subpackage" value="first"/>
   </properties>
</persistence-unit>

<persistence-unit name="second_PU">
   <properties>
      <property name="eclipselink.canonicalmodel.subpackage" value="second"/>
   </properties>
</persistence-unit>

<persistence-unit name="third_PU">
   <properties>
    <property name="eclipselink.canonicalmodel.subpackage" value="third"/>
   </properties>
</persistence-unit>

在部署项目后，您将获得：

ch.djan.lee.compute.entity.SpaceLog.first 
ch.djan.lee.compute.entity.SpaceLog.second 
ch.djan.lee.compute.entity.SpaceLog.third

使用Criteria编译错误JEE 6项目
