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:

java.lang.UnsupportedOperationException
