/** Do a harvest. Update the message parameter with the result
 * of the harvest./*from   w ww.  jav a  2s  .c  o m*/
 * NB: if delete is true, Tomcat must have write access, in order
 * to be able to delete the file successfully. However, a failed
 * deletion will not per se cause the subtask to fail.
 * @param version The version to which access points are to be added.
 * @param format The format of the file(s) to be harvested.
 * @param filePath The path to the file or directory to be harvested.
 * @param outputPath The directory in which to store output files.
 * @param delete True, if successfully harvested files are to be deleted.
 * @param results HashMap representing the result of the harvest.
 * @return True, iff the harvest succeeded.
