maven-enunciate-plugin生成文檔的空指針異常

我試圖運行maven-enunciate-plugin：1.26.2：docs並面臨NUllPointerException。maven-enunciate-plugin生成文檔的空指針異常

我唯一希望的是這裏所描述http://docs.codehaus.org/display/ENUNCIATE/Documentation+Only其文檔生成，所以我的pom.xml的是：

... 

<plugin> 
    <groupId>org.codehaus.enunciate</groupId> 
    <artifactId>maven-enunciate-plugin</artifactId> 
    <version>1.26.2</version> 
      <configuration> 
       <docsDir>${project.build.directory}/docs</docsDir> 
      </configuration> 
      <executions> 
       <execution> 
        <goals> 
         <goal>docs</goal> 
        </goals> 
       </execution> 
      </executions> 
</plugin> 

...

但是，它啓動：

我有以下建議：找到此特定版本插件的源代碼，並查看「DocsMojo」的第100行上發生了什麼。最有可能的是，你在配置中缺少一些參數。 –
