二、解决方案

从错误日志很明显的可以看出来是由于MyEclipse注册码过期导致的，所以这时就需要我们提供新的有效的注册码即可。

1、将所在设备的系统时间回滚至注册码有效期内以确保MyEclipse正常打开使用

2、在MyEclipse中新建一个java project （命名随意，例：abc）

3、在src目录下新建一个MyEclipseGen的类将如下的代码复制到该类中，并运行。

import java.text.DecimalFormat;
import java.text.NumberFormat;
import java.text.SimpleDateFormat;
import java.util.Calendar;

      
  public class MyEclipseGen {     

	  public static final void main(String[] args){          
			String subscriber = "Fgoatyy";  //subscriber        
			String licenseNum = "500";  //Number of Licenses        
			String version = "100"; //版本号        
			String subscriptionCode = getSubscriptionCode(subscriber, version , licenseNum ,true);        
			System.out.println(subscriptionCode);  //gLR8ZO-655055-62677056522757051    
			}     
		
		public static String getSubscriptionCode( String subscriber, String version, String licenseNum,  boolean selected)  {          
				Calendar cal = Calendar.getInstance();          
				cal.add(1, 3);  //年份加三年        
				cal.add(6, -1);  //日期减一        //当前日期20141226，到期日期则为20171225        
				NumberFormat nf = new DecimalFormat("000");          
				licenseNum = nf.format(Integer.valueOf(licenseNum));          
				String verTime = selected ? (new StringBuffer("-")).append(                  
						(new SimpleDateFormat("yyMMdd")).format(cal.getTime())).append("0").toString() : "-0812310";  
						String type = "YE3MB-";          
						String need = (new StringBuffer(String.valueOf(subscriber.substring(0, 1)))).append(type).append(version).append(licenseNum).append(verTime).toString();          
						String dx = (new StringBuffer(String.valueOf(need))).append("Decompiling this copyrighted software is a violation of both your license agreement and the Digital Millenium Copyright Act of 1998 (http://www.loc.gov/copyright/legislation/dmca.pdf). Under section 1204 of the DMCA, penalties range up to a $500,000 fine or up to five years imprisonment for a first offense. Think about it; pay for a license, avoid prosecution, and feel better about yourself.").append(subscriber).toString();         
						int suf = decode(dx);          
						String code = (new StringBuffer(String.valueOf(need))).append(String.valueOf(suf)).toString();
			return change(code);      
		}     
		
		private static int decode(String s) {          
			int i = 0;          
			char ac[] = s.toCharArray();          
			int j = 0;          
			for (int k = ac.length; j < k; j++)              
				i = 31 * i + ac[j];        
			return Math.abs(i);      
			}     
		
		private static String change(String s) {         
			byte abyte0[] = s.getBytes();          
			char ac[] = new char[s.length()];          
			int i = 0;          
			for (int k = abyte0.length; i < k; i++) {              
				int j = abyte0[i];              
				if (j >= 48 && j <= 57)                 
					j = ((j - 48) + 5) % 10 + 48;              
				else if (j >= 65 && j <= 90)                  
					j = ((j - 65) + 13) % 26 + 65;              
				else if (j >= 97 && j <= 122)                 
					j = ((j - 97) + 13) % 26 + 97;              
				ac[i] = (char) j;          
				}         
			return String.valueOf(ac);      
			}
		
              }

4、按照提示输入注册名（随意输入），然后会自动产生注册码。
