从Windows计算机上的Processing/Java运行Sox

Question

这可能很容易 - 但是此时它使我发疯。我正在尝试从Mac计算机上的处理运行顺利运行，没有问题。我需要将代码迁移到Windows 7机器，但由于某种原因无法使其工作。通过处理与终端交谈效果很好。我在正确的文件夹（草图数据文件夹也在Sox也被插入），因为我可以运行诸如" dir"等的命令，并打印正确的内容 - 但是一旦我尝试运行Sox.exe，任何事情都不会发生（获取（获取）出口值1）。直接从CMD终端运行Sox.exe工作正常。这是我想做的事情的示例：

void playBackYear (){
soxPlay = "cmd /c sox.exe year.wav -d";
  println (soxPlay);
 try {
    File workingDir = new File(sketchPath("data"));
    Process p=Runtime.getRuntime().exec(soxPlay, null, workingDir);
    p.waitFor(); 
    BufferedReader reader=new BufferedReader(
    new InputStreamReader(p.getInputStream())
      ); 
    String line; 
    while ( (line = reader.readLine ()) != null) 
    { 
      println(line);
    }
   int exitVal = p.waitFor();
   System.out.println("Exited with error code "+exitVal);
  } 
  catch(IOException e1) {
   System.err.println("Caught IOException: " + e1.getMessage());
   System.out.println( "error 1" );
  } 
  catch(InterruptedException e2) {
   System.err.println("Caught IOException: " + e2.getMessage());
   System.out.println( "error 2" );
  } 
}

所以问题是我在这里做错了什么？任何帮助都将不胜感激。

我编写了一个小型包装器应用程序，该应用程序包裹在Java中。如果您对整个项目感兴趣，请在GitHub上查看：Sox Java包装项目

这是我解决问题的方法：

private List<String> arguments = new ArrayList<String>();
// add sox arguments to this list above
public void execute() throws IOException {
    File soxBinary = new File(soXBinaryPath);
    if (!soxBinary.exists()) {
        throw new FileNotFoundException("Sox binary is not available under the following path: " + soXBinaryPath);
    }
    arguments.add(0, soXBinaryPath);
    logger.debug("Sox arguments: {}", arguments);
    ProcessBuilder processBuilder = new ProcessBuilder(arguments);
    processBuilder.redirectErrorStream(true);
    Process process = null;
    IOException errorDuringExecution = null;
    try {
        process = processBuilder.start();
        BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
        String line;
        while ((line = reader.readLine()) != null) {
            logger.debug(line);
        }
    } catch (IOException e) {
        errorDuringExecution = e;
        logger.error("Error while running Sox. {}", e.getMessage());
    } finally {
        arguments.clear();
        if (process != null) {
            process.destroy();
        }
        if (errorDuringExecution != null) {
            throw errorDuringExecution;
        }
    }
}
