MyEclipse提示过期“Your 30-day trial of MyEclipse has expired.”

今天MyEclipse提示过期了,MyEclipse Trial Expired.

网上找到了一个注册类可以生成Myeclipse注册码.

                                    public static void main(String[] args) {        

                                            try {        

                                                    System.out.println("please input register name:");        

                                                    BufferedReader reader = new BufferedReader(new InputStreamReader(        

                                                                    System.in));        

                                                    String userId = null;        

                                                    userId = reader.readLine();        

                                                    MyEclipseGen myeclipsegen = new MyEclipseGen();        

                                                    String res = myeclipsegen.getSerial(userId, "0");        

                                                    System.out.println("Serial:" + res);        

                                                    reader.readLine();        

                                            } catch (IOException ex) {        

                                            }        

                                    }        

                            }

运行后效果如下:

 

修改String res = myeclipsegen.getSerial(userId, "20"); 中"20"为"0"可以变成Number of Licenses为Unlimited.

 

然后

然后将刚才生成的序列号输入

点击下面的Finish即可

代码测试过了，可行！

从Myeclipse--》subscription information 即可进入update subscription界面。

ok，现在可以了吧？恭喜你！
