[JIRA] [workflow-plugin] (JENKINS-27893) Varargs mishandled in Groovy CPS

Sat, 11 Apr 2015 13:23:30 -0700

Thanks Jesse.

For the benefit of others I've tried the following:

node {  
    fn1("This should only be one string")
    fn1("Two", "Strings")
    fn2(["is", "This", "Three?"])
    fn3(["What", "about", "this?"] as String[])
    fn4(["Or", "perhaps", "this?"])
}

def fn1 (String... strs) {
    echo "${strs.size()}"
    def String s = ""
    for (int i = 0; i < strs.size(); i++) {
        s += "${strs[i]} "
    }
    echo "$s"
}

def fn2 (strs) {
    echo "${strs.size()}"
    def String s = ""
    for (int i = 0; i < strs.size(); i++) {
        s += "${strs[i]} "
    }
    echo "$s"
}

def fn3 (String[] strs) {
    echo "${strs.size()}"
    def String s = ""
    for (int i = 0; i < strs.size(); i++) {
        s += "${strs[i]} "
    }
    echo "$s"
}

def fn4 (List strs) {
    echo "${strs.size()}"
    def String s = ""
    for (int i = 0; i < strs.size(); i++) {
        s += "${strs[i]} "
    }
    echo "$s"
}

Here were the results:

is This Three?

Or perhaps this? 
Running: Allocate node : Body : End
Running: Allocate node : End

Finished: SUCCESS

I think I prefer the explicit List in fn4() so I shall go with that thanks.
