can you please help?

println("What is your name ");
def fName = System.console().readLine()
println("Hello" + fName)

Error in Groovy console

groovy> def fName = System.console().readLine() 
groovy> println("Hello" + fName)

System.console() works when running in terminal, but shouldn't work in an IDE, like Eclipse. A better way of getting a single line of input would be System.in.newReader().readLine()
