Java com.jcraft.jsch.ChannelSftp.throwstatus错误

我试图在其中创建一个

文件夹（folderName）和两个文件（file1.txt，file2.txt）

。创建文件夹和文件后，我更新其权限。首先更新文件的权限，然后更新文件夹的权限。但当调用文件夹权限进行更新时，引发异常。即使引发异常，也会正确更新文件夹和文件的权限。请帮助我找到如何防止此异常

更新1:

channelSftp.chmod（511，文件夹）//注释此行，正常工作，但无法更新文件夹的权限

更新2:
channelSftp.chmod（511，文件夹）//即使删除所有行并使用文件夹创建代码保留这一行，这一行仍然存在问题。文件夹已创建，但权限更新后出现异常

代码：

        String depDir = "/BaicDirectory";
        System.out.println("Processing ........ starts");

        Session session = new FTPComponent().getSession("");
        Channel channel = null;
        ChannelSftp channelSftp = null;
        try
        {
            session.connect();
            System.out.println("session is alive:" + session.isConnected());
            channel = session.openChannel("sftp");
            channel.connect();
            channelSftp = (ChannelSftp) channel;
            InputStream ftpLogIStream = new ByteArrayInputStream("file1.txt content".getBytes());
            InputStream processLogIStream = new ByteArrayInputStream("file2.txt content".getBytes());
            channelSftp.cd(depDir);
            String folder = "folderName";
            channelSftp.mkdir(folder);
            System.out.println("Folder is created");
            channelSftp.put(ftpLogIStream, depDir + "/" + folder + "/file1.txt");
            channelSftp.put(processLogIStream, depDir + "/" + folder + "/file2.txt");
            System.out.println("Files are created");

            channelSftp.cd(depDir);

您可以在WinSCP中更改权限吗？使用相同的凭据，我可以毫无问题地更新权限。更改文件（file1.txt和file2.txt）的权限有效，对吗？在WinSCP中，您可以更改文件和文件夹的权限，对吗？是的，我可以这样做。
