通过ProcessBuilder进行文档检索

Question

我正在尝试构建一个java进程，通过命令行执行产品。我已经编写了基于给定属性文件执行的进程。

        buildRoot = isWindowsOs() ? "C:" + "\\Program Files (x86)\\DocuSign, Inc\\Retrieve 3.2" : "\\Program Files (x86)\\DocuSign, Inc\\Retrieve 3.2" ;

        String[] command = new String [2];

        command[0] = "\""+buildRoot+ "\\" + docuSignAppName+"\"";
        logger.info(command[0].toString());
        //ADDED FOR EXPLANATION - "C:\Program Files (x86)\DocuSign, Inc\Retrieve 3.2\DocuSignRetrieve.exe"
        command[1] = arguments;
        logger.info(command[1].toString());

        ProcessBuilder processBuilder = new ProcessBuilder(command);
        logger.info("ProcessBuilder starting directory" +processBuilder.directory());
        processBuilder.redirectErrorStream(true);
        p = processBuilder.start();

        InputStream is = p.getInputStream();
        InputStreamReader isr = new InputStreamReader(is);
        stdout = new BufferedReader(isr);

一旦我传入构建出来的参数字符串，执行的代码看起来就像提供的样例，但是总是会导致错误返回到屏幕“缺失"accountid”参数“。

参数列表如下所示。

 /endpoint "Demo"      /userid "REMOVED"      /password "REMOVED"      /accountid "REMOVED"      /span "-1"      /spanfilter "Completed"      /statusfilter "Completed"      /fieldlog "LIST OF FIELDS"      /nstyle "EnvelopeID"      /save "MergedPdfWithoutCert"      /dir "D:\DocuSignStore"      /includeheaders "true" 

如有任何帮助或协助，将不胜感激。

这个解决方案是在StackOverflow关于与ProcessBuilder的共同问题的讨论中找到的。

我的问题是，我期望通过更改整个路径的放置，我可以运行可执行文件。因为我现在不确定的原因，这不像预期的那样有效。解决方案是运行CMD命令，该命令存在于任何windows操作系统的%PATH%上。

    String[] command = new String [2];

    command[0] = "\""+buildRoot+ "\\" + docuSignAppName+"\"";
    logger.info(command[0].toString());
    //ADDED FOR EXPLANATION - "C:\Program Files (x86)\DocuSign, Inc\Retrieve 3.2\DocuSignRetrieve.exe"
    command[1] = arguments;
    logger.info(command[1].toString());
    //This starts a new command prompt
    ProcessBuilder processBuilder = new ProcessBuilder("cmd","/c","DocusignRetreive.exe);
    //This sets the directory to run the command prompt from
    File newLoc = new File("C:/Program Files (x86)/DocuSign, Inc/Retrieve 3.2");
    processBuilder.directory(newLoc);
    logger.info("ProcessBuilder starting directory" +processBuilder.directory());
    processBuilder.redirectErrorStream(true);

    /*When the process builder starts the prompt looks like
     *C:\Program Files (x86)\DocuSign, Inc\Retrieve 3.2
     *Now DocusignRetrieve.exe is an executable in the directory to be run
     */
    p = processBuilder.start();
