Java 命令提示符命令抛出 "No such File or Directory"

Question

我目前正在开发一个应该执行一些控制台命令的程序。

我的代码是这样的:

  private String executeCommands(String[] commands)
  {
    String result = "";
    try
    {
      ProcessBuilder pb = new ProcessBuilder();
      String s = null;
      Charset charset = Charset.forName("IBM850");
      BufferedReader stdInput;
      Process proc;
      for (String command : commands)
      {
        System.out.println("Ausfuehrung von: " + command);
        pb.command(command);
        proc = pb.start();
        stdInput = new BufferedReader(new InputStreamReader(proc.getInputStream(), charset));
        while ((s = stdInput.readLine()) != null)
        {
          result += s;
        }
        System.out.println();
      }
    }
    catch (Exception ex)
    {
      result = ex.getMessage();
    }
    return result;
  }
  private void userLogIn(IUserInteraction userInteraction)
  {
    String[] command = { "svn auth --show-passwords" };
    String result = executeCommands(command);
    System.out.println(result);
  }

输出是“无法运行程序“svn auth --show-passwords”:error=2，没有那个文件或目录”，但是当我在控制台手动输入命令时，它起作用了。我做错了什么？

提前致谢!

经过一些尝试，我找到了一个可行的解决方案

String result
String line;
      Process process = Runtime.getRuntime().exec(command);
      Reader r = new InputStreamReader(process.getInputStream());
      BufferedReader in = new BufferedReader(r);
      while ((line = in.readLine()) != null)
        result += line;
      in.close();
