为什么JSch SCP不会将文件循环写入远程主机？

Question

我想（或者更确切地说）我必须使用JSch使用SCP将循环文件复制到远程主机。 我是这样做的：

public long writeFiles (Map<String, byte[]> files) {
    long count = 0;
    try {
        Channel channel = session.openChannel("exec");

        count = files.entrySet().stream().filter( k -> k.getKey() != null ).peek((k) -> {
            String command =
                    getProperty("scp.bin.path") + "scp -t " + getProperty("scp.target.path") +
                    "/" + k.getKey() + " ";
            System.out.println("Sending command: " + command);

            ((ChannelExec) channel).setCommand(command);
            try {
                channel.connect();
                System.out.println("Connected to channel to E@syMail Server " +
                                   getProperty("scp.host.ip"));
                command = "C0644 " + k.getValue().length + " " + k.getKey() + "\n";
                System.out.println("Sending C644 command: " + command);
                ((ChannelExec) channel).setCommand(command);
                final OutputStream out = channel.getOutputStream();
                out.write(command.getBytes());
                out.flush();
                out.write(k.getValue());
                out.flush();
                out.write(new byte[]{0}, 0, 1);
                out.flush();
                out.close();
            } catch (IOException ex) {
                logger.error(ex.toString());
            } catch (JSchException e) {
                logger.error(e.toString());
            }
            System.out.println("File written to " + getProperty("scp.host.ip") + ":" +
                               getProperty("scp.target.path") + "/" + k.getKey());
            ((ChannelExec) channel).setCommand("chmod " + getProperty("scp.chmod") + "-R " +
                                               k.getKey());

            channel.disconnect();
        }).count();
        session.disconnect();
    } catch (JSchException e) {
        logger.error(e.toString());
    }

    final MessageFormat mf = new MessageFormat(getProperty("msg.scp.done") + "\n");
    logger.info(mf.format(new Object[]{Long.valueOf(count),
                                       getProperty("scp.host.ip"),
                                       getProperty("scp.target.path")}));

    return count;
}

...但是当我查看目标文件夹时，文件不会复制到那里。 我究竟做错了什么？？我以示例JSch ScpTo

为导向

编辑1： 在执行SCP命令之前，我尝试以这种方式远程 ls ：

BufferedReader in=new BufferedReader(new InputStreamReader(channel.getInputStream()));
    ((ChannelExec) channel).setCommand("ls -lisa;");
    channel.connect();

    String msg=null;
    while((msg=in.readLine())!=null){
        System.out.println(msg);
    }

......而且它的工作做得很好！
