    .. versionadded:: 2016.3.0

    Make sure a repository is cloned to the given target directory and is
    a detached HEAD checkout of the commit ID resolved from ``rev``.

    name
        Address of the remote repository.

    rev
        The branch, tag, or commit ID to checkout after clone.
        If a branch or tag is specified it will be resolved to a commit ID
        and checked out.

    ref
        .. deprecated:: 2017.7.0
            Use ``rev`` instead.

    target
        Name of the target directory where repository is about to be cloned.

    remote : origin
        Git remote to use. If this state needs to clone the repo, it will clone
        it using this value as the initial remote name. If the repository
        already exists, and a remote by this name is not present, one will be
        added.

    user
        User under which to run git commands. By default, commands are run by
        the user under which the minion is running.

    password
        Windows only. Required when specifying ``user``. This parameter will be
        ignored on non-Windows platforms.

      .. versionadded:: 2016.3.4

    force_clone : False
        If the ``target`` directory exists and is not a git repository, then
        this state will fail. Set this argument to ``True`` to remove the
        contents of the target directory and clone the repo into it.

    force_checkout : False
        When checking out the revision ID, the state will fail if there are
        unwritten changes. Set this argument to ``True`` to discard unwritten
        changes when checking out.

    fetch_remote : True
        If ``False`` a fetch will not be performed and only local refs
        will be reachable.

    hard_reset : False
        If ``True`` a hard reset will be performed before the checkout and any
        uncommitted modifications to the working directory will be discarded.
        Untracked files will remain in place.

        .. note::
            Changes resulting from a hard reset will not trigger requisites.

    submodules : False
        Update submodules

    identity
        A path on the minion (or a SaltStack fileserver URL, e.g.
        ``salt://path/to/identity_file``) to a private key to use for SSH
        authentication.

    https_user
        HTTP Basic Auth username for HTTPS (only) clones

    https_pass
        HTTP Basic Auth password for HTTPS (only) clones

    onlyif
        A command to run as a check, run the named command only if the command
        passed to the ``onlyif`` option returns true

    unless
        A command to run as a check, only run the named command if the command
        passed to the ``unless`` option returns false

    output_encoding
        Use this option to specify which encoding to use to decode the output
        from any git commands which are run. This should not be needed in most
        cases.

        .. note::
            This should only be needed if the files in the repository were
            created with filenames using an encoding other than UTF-8 to handle
            Unicode characters.

    .. versionadded:: 2016.3.0

    Make sure a repository is cloned to the given target directory and is
    a detached HEAD checkout of the commit ID resolved from ``rev``.

    name
        Address of the remote repository.

    rev
        The branch, tag, or commit ID to checkout after clone.
        If a branch or tag is specified it will be resolved to a commit ID
        and checked out.

    ref
        .. deprecated:: 2017.7.0
            Use ``rev`` instead.

    target
        Name of the target directory where repository is about to be cloned.

    remote : origin
        Git remote to use. If this state needs to clone the repo, it will clone
        it using this value as the initial remote name. If the repository
        already exists, and a remote by this name is not present, one will be
        added.

    user
        User under which to run git commands. By default, commands are run by
        the user under which the minion is running.

    password
        Windows only. Required when specifying ``user``. This parameter will be
        ignored on non-Windows platforms.

      .. versionadded:: 2016.3.4

    force_clone : False
        If the ``target`` directory exists and is not a git repository, then
        this state will fail. Set this argument to ``True`` to remove the
        contents of the target directory and clone the repo into it.

    force_checkout : False
        When checking out the revision ID, the state will fail if there are
        unwritten changes. Set this argument to ``True`` to discard unwritten
        changes when checking out.

    fetch_remote : True
        If ``False`` a fetch will not be performed and only local refs
        will be reachable.

    hard_reset : False
        If ``True`` a hard reset will be performed before the checkout and any
        uncommitted modifications to the working directory will be discarded.
        Untracked files will remain in place.

        .. note::
            Changes resulting from a hard reset will not trigger requisites.

    submodules : False
        Update submodules

    identity
        A path on the minion (or a SaltStack fileserver URL, e.g.
        ``salt://path/to/identity_file``) to a private key to use for SSH
        authentication.

    https_user
        HTTP Basic Auth username for HTTPS (only) clones

    https_pass
        HTTP Basic Auth password for HTTPS (only) clones

    onlyif
        A command to run as a check, run the named command only if the command
        passed to the ``onlyif`` option returns true

    unless
        A command to run as a check, only run the named command if the command
        passed to the ``unless`` option returns false

    output_encoding
        Use this option to specify which encoding to use to decode the output
        from any git commands which are run. This should not be needed in most
        cases.

        .. note::
            This should only be needed if the files in the repository were
            created with filenames using an encoding other than UTF-8 to handle
            Unicode characters.
