Java 启用git lfs的Jgit克隆存储库不工作

当前设置

我有一个存储库，它是git lfs启用的。访问存储lfs内容的驱动器时，存在另一级别的身份验证。当我在命令提示符下运行下面的代码时，它会询问访问lfs内容的用户名和密码，如下所示

如果我们使用另一个没有对lfs内容进行身份验证的存储库，那么一切正常。 请告诉我如何禁止JGIT的身份验证，或者如何跳过LFS内容的获取。 如果我做错了什么，请告诉我

详情：
1） 使用以下JGit版本4.9.0.201710071750-r
2） 已安装git lfs

    String branch =  "refs/heads/master";
    System.out.println("Cloning from ["+url+"] branch ["+branch+"] to ["+destDir.toString()+"]");
    String workingDirPath = null;
    try {

            workingDirPath = FilenameUtils.normalize(destDir);
        } else {
            throw new Exception("Working directory for code sync not found : " + destDir);
        }

        recursivelyDelete(path.toFile());

这似乎与此错误有关：

查看代码，SmudgeFilter.downloadLfsResource（）使用getLfsConnection（），它处理SSH身份验证，但不处理HTTP身份验证

至少在我的测试中，下载失败，出现401异常（未授权），而不是提示输入凭据
