利用svn的补丁文件打包生成增量文件

下面的代码是maven版本

1. 创建patch.txt增量文件

保存到 文件目录下

比如 E:\aa\patch.txt

2. 编写java代码

package utils;

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.Set;
