Java IOException

Question

我正在执行一个下面的程序，它通过java调用shell，我得到excepton请帮助我。

程序：

import java.io.*; 
import java.util.*; 


public class ProcessExample { 

/** 
* @param args 
*/ 
public static void main(String args[]) throws IOException { 

     File file=new File("/opt/nilesh/fazal"); 


     ProcessBuilder processBuilder = new ProcessBuilder("./LicenseGen.sh --batchfile commands.txt"); 
     processBuilder.directory(file); 
     processBuilder.redirectErrorStream(true); 
     System.out.println("nilesh"); 
     Process process=processBuilder.start();  

     InputStream is = process.getInputStream(); 
     InputStreamReader isr = new InputStreamReader(is); 
     BufferedReader br = new BufferedReader(isr); 

     String line; 

     System.out.printf("Output of running %s is:", 
      Arrays.toString(args)); 

     while ((line = br.readLine()) != null) { 
     System.out.println(line); 
     } 

     OutputStream os=process.getOutputStream(); 
     OutputStreamWriter osw=new OutputStreamWriter(os); 
     BufferedWriter bw=new BufferedWriter(osw); 
     bw.write("create licensekey -x license-input.xml"); 

     while ((line = br.readLine()) != null) { 
     System.out.println(line); 
     } 

    } 

}

和异常

Answer 1

ProcessBuilder processBuilder = 
    new ProcessBuilder("./LicenseGen.sh","--batchfile","commands.txt"); 

您需要在命令和args作为单独字符串或列表通过。
