Question

我在使用java代码执行sh文件时遇到错误。从终端开始，它运行正常

sudo：没有tty存在且没有指定askpass程序

我的代码： -

package com.test;

import java.io.IOException;
import org.apache.commons.exec.CommandLine;
import org.apache.commons.exec.DefaultExecutor;
import org.apache.commons.exec.ExecuteException;

public class TestScript {

        int iExitValue;
        String sCommandString;

        public void runScript(String command){
            sCommandString = command;
            CommandLine oCmdLine = CommandLine.parse(sCommandString);
            DefaultExecutor oDefaultExecutor = new DefaultExecutor();
            oDefaultExecutor.setExitValue(0);
            try {
                iExitValue = oDefaultExecutor.execute(oCmdLine);
            } catch (ExecuteException e) {
                System.err.println("Execution failed.");
                e.printStackTrace();
            } catch (IOException e) {
                System.err.println("permission denied.");
                e.printStackTrace();
            }
        }

        public static void main(String args[]){
            TestScript testScript = new TestScript();
            testScript.runScript("sh /home/FTP-SCP-Project/shellscript.sh");
        }
    }

sh文件： -

sudo scp -i /home/FTP-SCP-Project/src/lib/demo.pem -r /home/FTP-SCP-Project/test-output3 user@xx.xxx.xx.xxx:/var/www/html/projects/demo_reports/reporttest112

我已经尝试了所有其他java代码，但他们给出了错误，而我给了他们所有权限，如chmod 777或755或600

    String Pemfilepath="/home/shubham/Experiment_zone/FTP-SCP-Project/src/lib/cuelogic.pem";
    String targetFolder = "/home/shubham/Experiment_zone/FTP-SCP-Project/test-output3";
    String[] command = { "sudo scp -i "+Pemfilepath+" -r "+targetFolder+" "+"ubuntu@54.152.13.148:/var/www/html/projects/kumo_reports/reporttest1"};   
//    String command = "ls";
    System.out.println(command[0]);
    Process process = Runtime.getRuntime().exec(new String[] { "sudo ", "scp ", "-i " ,Pemfilepath," ", "-r"," ",targetFolder," ","user@xx.xxx.xx.xxx:/var/www/html/projects/demo_reports/reporttest1" });                 
    BufferedReader reader = new BufferedReader(new InputStreamReader(         
        process.getInputStream()));                                          
    String s;                                                                
    while ((s = reader.readLine()) != null) {                                
      System.out.println("Script output: " + s);                             
    }

但是他们也给出了如下错误： -

线程“main”中的异常java.io.IOException：无法运行程序 “sudo”：error = 2，没有这样的文件或目录 java.lang.ProcessBuilder.start（ProcessBuilder.java:1047）at java.lang.Runtime.exec（Runtime.java:617）at java.lang.Runtime.exec（Runtime.java:485）at com.test.shelllocallaunch.main（shelllocallaunch.java:14）引起： java.io.IOException：error = 2，没有这样的文件或目录 java.lang.UNIXProcess.forkAndExec（Native Method）at java.lang.UNIXProcess。（UNIXProcess.java:187）at java.lang.ProcessImpl.start（ProcessImpl.java:130）at java.lang.ProcessBuilder.start（ProcessBuilder.java:1028）...还有3个

我观察到如果命令很小，就像ls一切都很好，但我的上面的命令没有执行，而它从终端正常工作。如果我遗漏任何内容，请帮忙

Answer 1

"echo "+pass+" | "+"sudo -S为我工作

我的完整代码如下所示： -

String pass = "\"Yourpassword\"";
                out.println("echo "+pass+" | "+"sudo -S scp -i "+Pemfilepath+" -r "+targetFolder+" "+"user@xx.xxx.xx.xxx:/var/www/html/projects/demoproject");

希望它会对你有所帮助:)。
