使用JDO的Maven GAE插件

Question

我使用JDO的Maven GAE插件，我開始使用jappstart示例（https://github.com/tleese22/google-app-engine-jappstart/blob/master/pom.xml） ，但由於某些原因，當我運行gae：run命令時，類不會增強，即使我已配置了增強功能。

<plugin> 
    <groupId>org.datanucleus</groupId> 
    <artifactId>maven-datanucleus-plugin</artifactId> 
    <version>1.1.4</version> 
    <configuration> 
     <mappingIncludes>**/jdo/*.class</mappingIncludes> 
     <verbose>true</verbose> 
     <enhancerName>ASM</enhancerName> 
     <api>JDO</api> 
    </configuration> 
    <executions> 
     <execution>      
      <phase>compile</phase>      
      <goals> 
       <goal>enhance</goal> 
      </goals> 
     </execution> 
    </executions> 
    <dependencies> 
     <dependency> 
      <groupId>org.datanucleus</groupId> 
      <artifactId>datanucleus-core</artifactId> 
      <version>${datanucleus.version}</version> 
      <exclusions> 
       <exclusion> 
        <groupId>javax.transaction</groupId> 
        <artifactId>transaction-api</artifactId> 
       </exclusion> 
      </exclusions> 
     </dependency> 
     <dependency> 
      <groupId>org.datanucleus</groupId> 
      <artifactId>datanucleus-rdbms</artifactId> 
      <version>${datanucleus.version}</version> 
     </dependency> 
     <dependency> 
      <groupId>org.datanucleus</groupId> 
      <artifactId>datanucleus-enhancer</artifactId> 
      <version>1.1.4</version> 
     </dependency> 
     <dependency> 
      <groupId>javax.jdo</groupId> 
      <artifactId>jdo2-api</artifactId> 
      <version>2.3-ec</version> 
     </dependency> 
    </dependencies> 
</plugin> 

例外：

javax.jdo.JDOUserException: Persistent class "Class com.my.Entity does not seem to have been enhanced. You may want to rerun the enhancer and check for errors in the output." has no table in the database, but the operation requires it. Please check the specification of the MetaData for this class. 

Answer 1

我有什麼毛病我的映射包括。現在，如果實體處於具有姓氏實體的包中（例如com.my.app.entity），它就可以工作：

<mappingIncludes>**/entity/*.class</mappingIncludes>
