java - 如何从 .bat 进程获取输出以显示在 JTextPane 中？

Question

我的程序要求我运行一个 .bat 文件来编译 java 源代码。这运行良好，但是我正在寻找一种解决方案，它将获取 compile.bat 的输出(和可能的错误)并将其添加到 GUI 上的文本 Pane 中。我有以下代码，但是当执行该过程时，不会向 Pane 打印任何内容，也没有任何错误。

GenerationDebugWindow.main(null);

Process process = rut.exec(new String[] {file.getAbsolutePath() + "\\compile.bat"});
Scanner input = new Scanner(process.getInputStream());

InputStream is = process.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader reader = new BufferedReader(isr);

String line;
int exit = -1;

while ((line = reader.readLine()) != null) {
    // Outputs your process execution
    try {
        exit = process.exitValue();
        GenerationDebugWindow.writeToPane(line);
        System.out.println(line);
        if (exit == 0)  {
            GenerationDebugWindow.writeToPane("Compilation Finished!");
            if(new File(file + "/mod_" + WindowMain.modName.getText()).exists()){
                GenerationDebugWindow.writeToPane("Compilation May Have Experienced Errors.");
            }
        }
    } catch (IllegalThreadStateException t) {

    }
}

生成调试窗口

private static JTextPane outputPane;
public static void writeToPane(String i){
    outputPane.setText(outputPane.getText() + i + "\r\n");
}

使用:

Runtime.getRuntime().exec( "cmd.exe /C " + file.getAbsolutePath() + "\\compile.bat" );
