将命令写入运行进程

Question

我已经搜索了很多答案，但没有发现任何真正有用的东西，我发现的线程都是僵尸。

我的问题：我正在为Bukkit服务器创建一个UI，但是对于最终用户在服务器中执行命令，我必须使用OutputStreamWriter写入该进程。 我有所有代码，但命令没有被发送到进程。

到目前为止，这是我用来执行服务器并获取所有流的代码：

@SuppressWarnings("null")
private void startServer() throws InterruptedException, IOException {
    setTitleText("BukkitUI by Beatsleigher [Starting...]");
    setStatusImg(ServerState.BOOTING);
    Thread.sleep(1000);
    setTitleText("BukkitUI by Beatsleigher [Loading components...]");
    runServer = true;
    process = new ProcessBuilder();
    // Set attibutes
    process.redirectErrorStream(true);
    java.util.List<String> jvmArgs = new ArrayList<>(4);
    jvmArgs.add(JVMManager.getJava().toString()); // If you don't know what this does, you should not consider yourself a programmer.
    jvmArgs.add("-jar");
    jvmArgs.add(JVMManager.getProcessedInitHeapSize()); // Add Java VM arg[0]
    //jvmArgs.add(JVMManager.getProcessedMaxHeapSize()); // Add Java VM arg[1]
    jvmArgs.add(PreferenceManager.getBukkitLocation().getAbsolutePath()); // Add Java VM arg[2]
    jvmArgs.add("-o"); // Add CraftBukkit arg[0]
    jvmArgs.add("true"); // Add CraftBukkit arg[1]
    process.command(jvmArgs);
    // Start process
    pr = process.start();
    setTitleText("BukkitUI by Beatsleigher [Running]");
    consoleWriter = new BufferedWriter(new OutputStreamWriter(pr.getOutputStream()));
    processServer();
}

private void processServer() throws IOException {
    new Thread() {
        @Override
        public void run() {
            try {
                setStatusImg(ServerState.ONLINE);
                jTextPane1.setText("");
                consoleReader = new BufferedReader(new InputStreamReader(pr.getInputStream()));
                while ((consoleOutput = consoleReader.readLine()) != null && (runServer)) {
                    jTextPane1.setText(jTextPane1.getText() + "\n" + consoleOutput);
                    highlight();
                }
                jTextPane1.setText(jTextPane1.getText() + "\n[INFO] [BukkitUI] Server has Stopped!");
                highlight();
                stopServer();
            } catch (IOException ex) {
                Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
                pr.destroy();
                try {
                    consoleReader.close();
                } catch (IOException ex1) {
                    Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex1);
                }
                setStatusImg(ServerState.OFFLINE);
                setTitleText("BukkitUI by Beatsleigher [ERROR! Server has stopped!]");
            }
        }
    }.start();
}

服务器启动并运行正常，我得到了我需要的所有进程输出，但是，如前所述，我使用以下代码发送到控制台的任何命令都不起作用。

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
    String inputCmd = jTextField1.getText();
    try {
        if (inputCmd != null | !inputCmd.equals("")) {
            if (inputCmd.startsWith("/")) {
                String[] cmd = inputCmd.split("/");
                consoleWriter.write(cmd[1]);
                clearCmd();
                return;
            } else if (inputCmd.startsWith("cmd;")) {
                String[] cmd = inputCmd.split("cmd;");
                consoleWriter.write(cmd[1]);
                clearCmd();
                return;
            }
            if (inputCmd.startsWith("bcast;")) {
                String[] msg = inputCmd.split("bcast;");
                consoleWriter.write("broadcast " + msg[1]);
                clearCmd();
                return;
            }
            if (inputCmd.startsWith("appnd;")) {
                String[] msg = inputCmd.split("appnd;");
                jTextPane1.setText(jTextPane1.getText() + "\n[BUKKITUI] " + msg[1]);
                clearCmd();
                return;
            }                
            if (inputCmd.equals("--h")) { showHelp(); clearCmd(); return; }

            consoleWriter.write("say " + inputCmd);
            clearCmd();
        }
    } catch (IOException ex) {
        Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
    } 

非常感谢任何有关此事的帮助。
