Question

I am trying to run below code in jenkins build flow

def generator = { String alphabet, int n ->
new Random().with {
(1..n).collect { alphabet[ nextInt( alphabet.length() ) ] }.join() 
} 
}
pattern = '0x' + generator( (('A'..'F')+('0'..'9')).join(), 16 )
plintln "Random Pattern Created :" + pattern

output is below
