ant Implementing iterations in

because ant Iteration itself is not supported , So we need to use a third-party library ant-contrib To implement the iteration function .
download ant-contrib, And will ant-contrib-1.0b3.jar Copy the document to ANT The installation directory .
Download address ：

http://sourceforge.net/projects/ant-contrib/files/

http://pan.baidu.com/s/1pJKDeyR

I'm here ant-contrib-1.0b3.jar Put it in ant Installation directory lib Under the table of contents .

Sample code ：

    
	
     
	
     
	
	
     
	
     
        
      
            
       
        
      
    
     

    
     
	
     
	
	
     
		
      
		
      
   	
     
   	
	
     
  		
      
       channel = ${channel}
      
	
     

    

Running effect ：
