Hi, all!

I'm new in Groovy and Script runner. I have the list of strings and I can't iterate them with cycles "for", "foreach" etc.:

data = ["1", "2", "3", "4", "5"]
for (e in data) {
println e

And as result I get:  no return value

Can you assist me in this issue?

I think the issue is that println is going to catalina.out, whereas Evgeniy is expecting it to be returned in the UI. The script console will return the value of the last statement executed, which for println, is nothing.

If you tail your catalina.out you should see it there, but that's not easy to debug like that.


Just use the syntax like this:

data.each() {
	println "${it}"

You shoud read the docs about looping in groovy as well smile (http://groovy.codehaus.org/Looping).

You could use the simple Java syntax as well, but then it wouldn't be that fancy smile

Thank you. It's works)

Friday Fun: What's your favourite beer/drink
