  - ### instance

    protected static GrapeEngine instance
    Lazily created grape engine instance.

- ## Constructor Details

    public Grape()

- ## Method Details

  - ### getEnableGrapes

    public static boolean getEnableGrapes()
    This is a static access kill-switch. All the static shortcut methods in this class will be disabled if this property is set to false. By default, it is set to true.

  - ### setEnableGrapes

    public static void setEnableGrapes(boolean enableGrapes)
    This is a static access kill-switch. All the static shortcut methods in this class will be disabled if this property is set to false. By default, it is set to true.

  - ### getEnableAutoDownload

    public static boolean getEnableAutoDownload()
    This is a static access auto download enabler. It will set the 'autoDownload' value to the passed in arguments map if not already set. If 'autoDownload' is set the value will not be adjusted.

    This applies to the grab and resolve calls.

    If it is set to false, only previously downloaded grapes will be used. This may cause failure in the grape call if the library has not yet been downloaded

    If it is set to true, then any jars not already downloaded will automatically be downloaded. Also, any versions expressed as a range will be checked for new versions and downloaded (with dependencies) if found.

    By default, it is set to true.

  - ### setEnableAutoDownload

    public static void setEnableAutoDownload(boolean enableAutoDownload)
    This is a static access auto download enabler. It will set the 'autoDownload' value to the passed in arguments map if not already set. If 'autoDownload' is set the value will not be adjusted.

    This applies to the grab and resolve calls.

    If it is set to false, only previously downloaded grapes will be used. This may cause failure in the grape call if the library has not yet been downloaded.

    If it is set to true, then any jars not already downloaded will automatically be downloaded. Also, any versions expressed as a range will be checked for new versions and downloaded (with dependencies) if found. By default, it is set to true.

  - ### getDisableChecksums

    public static boolean getDisableChecksums()
    Global flag to ignore checksums. By default, it is set to false.

  - ### setDisableChecksums

    public static void setDisableChecksums(boolean disableChecksums)
    Set global flag to ignore checksums. By default, it is set to false.

  - ### getInstance

    public static GrapeEngine getInstance()
    Returns the shared grape engine instance.
    Returns:
      the shared engine, or `null` if grapes are unavailable

  - ### grab

    public static void grab(String endorsed)
    Grabs a dependency expressed as a single string.

    Recognized forms:

    - Maven shorthand: `group:module:version[:classifier][@ext]`
    - Ivy shorthand: `group#module;version`
    - Endorsed module: a bare module name (legacy; resolves under the `groovy.endorsed` group at the current Groovy version)
    Parameters:
      `endorsed` - the dependency notation

  - ### grab

    public static void grab(Map<String,Object> dependency)
    Grabs a single dependency.
    Parameters:
      `dependency` - the dependency descriptor

  - ### grab

    public static void grab(Map<String,Object> args, Map... dependencies)
    Grabs one or more dependencies using the supplied arguments.
    Parameters:
      `args` - grab arguments
      `dependencies` - dependency descriptors

  - ### enumerateGrapes

    public static Map<String,Map<String,List<String>>> enumerateGrapes()
    Enumerates locally available grapes.
    Returns:
      grapes grouped by organization and module

  - ### resolve

    public static URI[] resolve(Map<String,Object> args, Map... dependencies)
    Resolves dependency coordinates to URIs.
    Parameters:
      `args` - resolve arguments
      `dependencies` - dependency descriptors
    Returns:
      the resolved artifact URIs

  - ### resolve

    public static URI[] resolve(Map<String,Object> args, List depsInfo, Map... dependencies)
    Resolves dependency coordinates to URIs while optionally collecting dependency information.
    Parameters:
      `args` - resolve arguments
      `depsInfo` - optional dependency metadata sink
      `dependencies` - dependency descriptors
    Returns:
      the resolved artifact URIs

  - ### listDependencies

    public static Map[] listDependencies(ClassLoader cl)
    Lists dependencies associated with the supplied class loader.
    Parameters:

    Returns:
      the dependency descriptors

  - ### addResolver

    public static void addResolver(Map<String,Object> args)
    Adds a resolver to the shared grape engine.
