需求：用JAVA语言实现WINDOW和LINUX系统下自动安装PERL组件的功能。
 public void execNormalInstall(String modulename) {
        Runtime runTime = Runtime.getRuntime();
        Process process = null;
        try {
            if (System.getProperty("os.name").toUpperCase().indexOf("WINDOWS") >= 0) {
                modulename = modulename.replaceAll("::", "-");
                String path = CorePlugin.getDefault().getPreferenceStore().getString(ITalendCorePrefConstants.PERL_INTERPRETER);//安装PERL的目录 ex:E:\Perl\bin
                path = path.substring(0, path.lastIndexOf("\\"));
                process = runTime.exec("cmd /c start /D" + path + "\\" + " ppm install " + modulename);
              // process = runTime.exec("cmd /c start /D" + path + "\\" + " /B ppm install " + modulename);// "/B"不打开DOS窗口
            } else if (System.getProperty("os.name").toUpperCase().indexOf("LINUX") >= 0) {
                String command = "perl -MCPAN -e 'install " + modulename + "'";
                openTerminal(command, process);
            }
        } catch (Exception e) {
            MessageBoxExceptionHandler.process(e);
        }
    }
  public static void openTerminal(String command, Process process) {
        String terminal = System.getenv("TERM");
        try {
            process = Runtime.getRuntime().exec(new String[] { terminal, "-e", command + "; $SHELL" });
            process.waitFor();
        } catch (IOException e) {
            System.out.println(e.getMessage());
        } catch (InterruptedException e) {
            // TODO: handle exception
        }
当然如果是linux，需要安装gcc的编译器，之前不懂PERL，也没用过LINUX，浪费好几天，在LINUX下还有个权限问题。
