    • Type: Bug
    • Resolution: Unresolved
    • Priority: Major
    • Component/s: workflow-cps-plugin
    • Environment:
      Jenkins: 2.387.2
      OS: Windows Server 2019 - 10.0
      Java: 17.0.4.1 - Eclipse Adoptium (OpenJDK 64-Bit Server VM)
      workflow-cps: 3653.v07ea_433c90b_4

      Groovy methods with:

      • a parameter with the same name as the method
      • an optional parameter
      • called without providing the optional parameter

      apparently aren't being handled correctly anymore. I'm not sure exactly when the behavior changed, but the following example works on:

      • Jenkins 2.346.3 / Pipeline: Groovy 2759.v87459c4eea_ca_  / Java 8

      but fails on:

      • Jenkins 2.387.2 / Pipeline: Groovy Version 3653.v07ea_433c90b_4 / Java 17

      It also works fine in the Jenkins Script Console in both versions.

      Example pipeline script:

      def foo(String foo, Map options = null) {
    println("foo: $foo with: $options");
}

def bar(String foo, Map options = null) {
    println("bar: $foo with: $options");
}

bar("test1", [:]);   // Works: no parameters named 'bar'
bar("test2");        // Works

foo("test3", [:]);   // Works: optional parameter provided
foo("test4");        // Fails: exception thrown here

      This should print:

       

      bar: test1 with: [:]
bar: test2 with: null
foo: test3 with: [:]
foo: test4 with: null

       

      Instead, the final line throws an exception:

      hudson.remoting.ProxyException: groovy.lang.MissingMethodException: No signature of method: java.lang.String.call() is applicable for argument types: (java.lang.String, null) values: [test4, null]
Possible solutions: wait(), chars(), any(), trim(), find(), size()
