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>
