Hey, i try to trim each string item of an list in groovy
list.each() { it = it.trim(); }
But this only works within the closure, in the list the strings are still " foo", "bar " and " groovy ".
How can i achieve that?

String interpolation. Any Groovy expression can be interpolated in all string literals, apart from single and triple-single-quoted strings. Interpolation is the act of replacing a placeholder in the string with its value upon evaluation of the string. The placeholder expressions are surrounded by ${} .
[:] creates an empty Map. The colon is there to distinguish it from [] , which creates an empty List. This groovy code: def foo = [:]
list = list.collect { it.trim() }
You could also use the spread operator:
def list = [" foo", "bar ", " groovy "]
list = list*.trim()
assert "foo" == list[0]
assert "bar" == list[1]
assert "groovy" == list[2]
