在SSH会话中执行命令时打印命令输出

Question

我使用SSHJ打开SSH会话并执行命令。 我遇到了一个问题，我无法获取命令的输出。谁能帮我吗？

SSHClient ssh = new SSHClient(); 
ssh.addHostKeyVerifier(  
                    new HostKeyVerifier() {  
                        public boolean verify(String arg0, int arg1, PublicKey arg2) {  
                            return true;  
                        }  
                    }  
            );
            ssh.connect(this.hostName, this.port);
            ssh.authPassword("santera", "santera1");
            //final Console con = System.console();
             Session session = ssh.startSession();
            session.allocateDefaultPTY();
             Shell shell = session.startShell();
             Expect expect = new ExpectBuilder()
                        .withOutput(shell.getOutputStream())
                        .withInputs(shell.getInputStream(), shell.getErrorStream())
                        .withEchoInput(System.out)
                        .withEchoOutput(System.err)
                        .withExceptionOnFailure()
                        .build();

                expect.sendLine("script test.txt");
                expect.expect(contains("%"));

                expect.sendLine("ls -l"); // ls -l is a command
                expect.expect(contains("%")); // % is a prompt

我想将命令的输出从'command'转换为'prompt'。
