Pipeline: Groovy closure returns early after method call

[Mark J. Becker]

Hi,

I have a problem executing closures in my pipeline, since they return early. I could break down the problem to the following minimal example:

class Foo {
    Closure<String> cl = { String a ->
        return "Say: ${this.bar(a)}"
    }
    String bar(String a) {
        return "Hello ${a}."
    }
}
Foo f = new Foo()
String output = f.getCl()("World")
echo(output)

The expected output of this code is "Say: Hello World.", which it returns when I execute it locally in native Groovy. However, in a Jenkins pipeline job the code returns "Hello World.".

I assume that the closure directly returns the output of the this.bar(a) method call.

After having already reported a ticket for this issue, does somebody know more about this issue? Is there a workaround available?

Thanks.
