  - ### isTraceTreeWalker

    @Input public boolean isTraceTreeWalker()
    Specifies that all tree walker rules call `traceIn`/`traceOut`.

  - ### setTraceTreeWalker

    public void setTraceTreeWalker(boolean traceTreeWalker)

  - ### getMaxHeapSize

    @Internal public String getMaxHeapSize()
    The maximum heap size for the forked antlr process (ex: '1g').

  - ### setMaxHeapSize

    public void setMaxHeapSize(String maxHeapSize)

  - ### setArguments

    public void setArguments(List<String> arguments)

  - ### getArguments

    @Input public List<String> getArguments()
    List of command-line arguments passed to the antlr process
    Returns:
      The antlr command-line arguments

  - ### getOutputDirectory

    @OutputDirectory public File getOutputDirectory()
    Returns the directory to generate the parser source files into.
    Returns:
      The output directory.

  - ### setOutputDirectory

    public void setOutputDirectory(File outputDirectory)
    Specifies the directory to generate the parser source files into.
    Parameters:
      `outputDirectory` - The output directory. Must not be null.

  - ### getAntlrClasspath

    @Classpath public FileCollection getAntlrClasspath()
    Returns the classpath containing the Ant ANTLR task implementation.
    Returns:
      The Ant task implementation classpath.

  - ### setAntlrClasspath

    protected void setAntlrClasspath(FileCollection antlrClasspath)
    Specifies the classpath containing the Ant ANTLR task implementation.

  - ### execute

    public void execute(InputChanges inputChanges)
    Generate the parsers.
    Since:
      6.0

  - ### setSource

    public void setSource(FileTree source)
    Sets the source for this task. Delegates to `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.
    Since:
      4.0

  - ### 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

    @Internal("tracked via stableSources") 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.

    The `PathSensitivity` for the sources is configured to be `PathSensitivity.ABSOLUTE`. If your sources are less strict, please change it accordingly by overriding this method in your subclass.

    Overrides:
      `getSource` in class `SourceTask`
    Returns:
      The source.

  - ### getStableSources

    @SkipWhenEmpty @IgnoreEmptyDirectories @PathSensitive(RELATIVE) @InputFiles protected FileCollection getStableSources()
    The sources for incremental change detection.
