在项目研发的过程中，我们往往会同时写多个版本的情况，而如果我们在低版本bug的同时新版本可能也存在这个bug，那么，一般解决方案有两个，要么是将最新的代码实时与新版本同步，要么是在新版本要上线的时候对新老版本的bug进行对比。理论上讲，第一种方案相对来说，出错的概率要小一些。所以下面我来介绍一下对于第二种方案的思路。
主体思路
首先，我们要知道，比较两个项目的异同一般是指的对两个版本的异同点进行比较，两个完全不同的项目是没有必要比较异同的。那么比较这个系统的两个不同版本主要关心的点有哪些呢？
1、新版本相对于旧版本少的文件：这很有可能是旧版本为了满足一定的需求而创建的，而这个需求在新版本中也有。
2、相同代码文件中代码的不同之处。
新版本相较于旧版本多出来的文件我们是不需要考虑的。
针对上面两个关注点，可以采取以下两种方案
GIT比较法
git 追踪到文件，就可以很好的满足到上面提到的两种情况。
假设我们的两个版本为1.0和2.0，首先，创建一个1.0项目的副本目录（包含git文件夹），同时也创建一个2.0项目的副本目录（包含git文件夹），然后将1.0副本代码替换为2.0副本代码，然后利用可视化提交界面，一个个的进行区别查看，然后根据现有的逻辑进行补充。
逻辑如图所示：
当我们使用Git进行异同点检查的时候，可能遇到的指令有 git revert（撤销历史提交），因为对于1.0的git来说，1,.0中新增的文件，对于2.0的代码进行检查显示的就是该文件被删除了，所以我们需要对删除的文件的删除行为进行撤销。
查看思路：
1、unknown的东西就不管，因为这是最新版多的东西
2、miss的东西可能是缺少的，也可能是修改的，所以这里不能盲目git revert。
3、modifined是变化的，如果是变少了：本质上就是1.0修复时加上去的，所以要考虑加到2.0中
注意事项：
1、确保两个版本的代码都是最新的（1.0和2.0）
2、一定不要点确认提交，毕竟我们只是使用git的比较机制
3、看准比较的究竟那边是本地当前的和以前的，这里我推荐使用可视化工具
4、修改的过程中可能会有改错的情况，所以在改完之后要启动所有项目试一下。
Java静态代码分析法
该方法目前只做到了能比较两个java项目的相似度，目前对自动化变更代码尚有技术的不可预知性。
分析Java代码
首先，定义出一个Java代码的项目结构对应的简单对象。
给出Java项目结构所需简单对象
