我的代码是

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

public class ProcessExample {

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

       File file=new File("/opt");
      // List<String> list=new List<String>();
       ProcessBuilder processBuilder = new ProcessBuilder("./LicenseGen.sh");
       processBuilder.directory(file);

        Process process=processBuilder.start();      
       //processBuilder.command("create licensekey -x license-input.xml");
       //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);
       }

     }
}

推荐答案

您不能直接执行脚本，因为它必须由像bash这样的shell解释。
注意bash是可执行的。

You can't execute the script directly since it has to be interpreted by a shell like bash. Note that bash is an executeable.

ProcessBuilder pb = new ProcessBuilder("/bin/bash", "/path/LicenseGen.sh");
