org.bsc.maven.maven-processor-plugin不适用于java 1.7及以上版本

Question

我有一个GitHub repository，我主持一些Hibernate示例并生成JPA MetaModel类我一直使用下面的Maven插件：

<plugin> 
    <groupId>org.bsc.maven</groupId> 
    <artifactId>maven-processor-plugin</artifactId> 
    <version>2.0.5</version> 
    <executions> 
     <execution> 
      <id>process</id> 
      <goals> 
       <goal>process</goal> 
      </goals> 
      <phase>generate-sources</phase> 
      <configuration> 
       <outputDirectory>target/generated-sources/java/</outputDirectory> 
       <processors> 
        <processor>org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor 
        </processor> 
       </processors> 
      </configuration> 
     </execution> 
    </executions> 
</plugin> 

在Java 1.6一切运行得很好，但是当我切换到Java 1.7，我得到以下错误：

元模型类生成两次：

D:\wrk\vladmihalcea\vladmihalcea.wordpress.com\hibernate-facts\target\classes\com\vladmihalcea\hibernate\model\bag\Child_.java 
D:\wrk\vladmihalcea\vladmihalcea.wordpress.com\hibernate-facts\target\generated-sources\java\com\vladmihalcea\hibernate\model\bag\Child_.java 

你知道任何可能的修复吗？

我设法得到它的工作是这样的：

的Maven的处理器插件为JDK 1.6激活，而默认情况下它是Maven的编译器插件应用JPA元模型后处理。
