### execute

    public void execute()
                 throws BuildException

  Description copied from class: `Task`
  Called by the project to let the task do its work. This method may be called more than once, if the task is invoked more than once. For example, if target1 and target2 both depend on target3, then running "ant target1 target2" will run all tasks in target3 twice.

    `BuildException` - if something goes wrong with the build

### getArchiveFile

  Helper class to retrieve the path used to store the JavaCC.zip which is different from versions.

  Parameters:
    `home` - the javacc home path directory.
  Returns:
    the file object pointing to the JavaCC archive.
  Throws:
    `BuildException` - thrown if the home directory is invalid or if the archive could not be found despite attemps to do so.
