How to check file Exist or not?

Question

Here I'm trying to check whether the file exist or not.but the below code doesn't return anything and also get the error at this line

Error line : Boolean t = fileslist.Exists()

   start()
    def start(){
    def store;
    boolean success;
    def ftpClient = new FTPClient()
    ftpClient.connect(server)
    ftpClient.login(user,pass) 
     ftpClient.enterLocalPassiveMode()
     FTPFile[] fileslist = ftpClient.listFiles("/Sample.txt")
     ftpClient.setFileType(FTP.BINARY_FILE_TYPE)
     filelist.each{
          it.exists()
       }  
     ftpClient.disconnect() 

    }

Thanks

Your code snippet doesn't show what you want to do with the file if it exists... What are you trying to do? Also, why are you listing files using a file name path? — ernest_k, Apr 17 '18 at 11:28

You can verify that a file exists by checking that the returned array is not empty:

FTPFile[] fileslist = ftpClient.listFiles("/Sample.txt")

if(fileslist)
    print "File exists"
else(fileslist)
    print "File does not exist"

Alternatively, you can check the results and find the name you're interested in:

FTPFile[] fileslist = ftpClient.listFiles("/")

def matchedFiles = Arrays.asList(fileslist).grep(it.name == 'Sample.txt')

The below will return a list with matching file objects

You may need to confirm that an exception is not raised when the file isn't found, in which case it may be preferable to use the second alternative. – ernest_k Apr 17 '18 at 11:53
