          @OutputDirectory
          public File getOutputDirectory()

      Returns the directory to generate the parser source files into.
      Returns:

          public void setOutputDirectory(File outputDirectory)

      Specifies the directory to generate the parser source files into.
      Parameters:

    - #### setSource

          public void setSource(Object source)

      Sets the source for this task. Delegates to `SourceTask.setSource(Object)`. If the source is of type `SourceDirectorySet`, then the relative path of each source grammar files is used to determine the relative output path of the generated source If the source is not of type `SourceDirectorySet`, then the generated source files end up flattened in the specified output directory.
      Overrides:
        `setSource` in class `SourceTask`
      Parameters:
        `source` - The source.

    - #### getSource

          @SkipWhenEmpty
          public FileTree getSource()

      Returns the source for this task, after the include and exclude patterns have been applied. Ignores source files which do not exist.
      Overrides:
        `getSource` in class `SourceTask`
      Returns:
        The source.
