我尝试下面的代码连接到SFTP服务器连接到SFTP服务器使用sinet工厂
final String sftpURL = <<my hostname here>>;
final String username = <<username here>>;
final String password = <<password here>>;
SshParameters params = new SshParameters(sftpURL,username,password);
Sftp ftp = new Sftp(params);
// Connect, upload PNG images and release the connection.
ftp.connect();
ftp.disconnect();
尝试连接时它被扔下面的错误:::

的上面的代码在几个月前工作。但现在它抛出了错误。我也下载了最新版本的sinet-factory.jar。有人能帮我解决这个问题吗？
