All Implemented Interfaces:
  Cloneable

    public class RccTask

extends org.apache.tools.ant.Task

Hadoop record compiler ant Task

This task takes the given record definition files and compiles them into java or c++ files. It is then up to the user to compile the generated files.

The task requires the `file` or the nested fileset element to be specified. Optional attributes are `language` (set the output language, default is "java"), `destdir` (name of the destination directory for generated java/c++ code, default is ".") and `failonerror` (specifies error handling behavior. default is true).

#### Usage

     <recordcc
           destdir="${basedir}/gensrc"
           language="java">
       <fileset include="**\/*.jr" />
     </recordcc>
