java将git代码导入svn并覆盖trunk中的内容

java操作git仓库的代码参见：

java操作svn的maven依赖为：

        
 
            
  
   org.tmatesoft.svnkit
  
            
  
   svnkit
  
            
  
   1.8.7
  
        
 

git代码导入svn并覆盖trunk的步骤：
   1、通过jgit库操作git仓库，并将要导入svn的tag或分支checkout
   2、传递git仓库的本地文件夹目录地址给操作svn的方法，在方法中完成后续步骤
