    public static void mkdirs(ChannelSftp ch, String path) {
    try {
        String[] folders = path.split("/");
        if (folders[0].isEmpty()) folders[0] = "/";
        String fullPath = folders[0];
        for (int i = 1; i < folders.length; i++) {
            Vector ls = ch.ls(fullPath);
            boolean isExist = false;
            for (Object o : ls) {
                if (o instanceof LsEntry) {
                    LsEntry e = (LsEntry) o;
                    if (e.getAttrs().isDir() && e.getFilename().equals(folders[i])) {
                        isExist = true;
                    }
                }
            }
            if (!isExist && !folders[i].isEmpty()) {
                ch.mkdir(fullPath + folders[i]); 
            }
            fullPath = fullPath + folders[i] + "/";
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

I used this implementation to create nested folders.

I tried not to use Exception. Keep in mind that filesystem is linux based. The OP already found a solution but I wanted to append to it. Simply I do mkdir if the folder that I wanted to create doesn't exist in "ls" result.
