It seems the groovy spread '*' operator causes compilation errors when it is used in Pipeline. This example code does not seem to compile:
def fn (String... strs) { println "${strs.size()}" } def s = ["This should only be one string", "this is another"] def n = fn(*s) print(n)
The exception we get is:

[JENKINS-46163] Pipeline CPS Groovy does not seem to support spread '*' operator
Justin Rainwater
added a comment - I just ran into this as well and I'm disappointed to see this was closed as a dupe when it's a different command. Any solution abayer?

However, the spread * and spread-dot *. operators are separate, not the same. See the below links for reference.

Is there any solution for this?

added a comment - I have created a PR to add support for spread list:
def foo = [*x, 1, 2]
spread map:
def foo = [*:x, a: 'a']
and spread in arguments
sum(*args, 42)

https://github.com/cloudbees/groovy-cps/pull/116 A fix for this issue has been released in Pipeline: Groovy plugin version 3536.vb_8a_6628079d5.
Not sure why this was marked as a duplicate of JENKINS-33051 - "spread" and "star-dot" look similar, but are completely different operators. Spread (Star preceding a collection in function argument list) is used for passing arrays as individual arguments when calling functions while star-dot (A star preceded by a collection and followed by a dot and a method reference) is used to iterate over collection members calling a method on each one.
