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()

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
