Got "Ambiguous method overloading" for trampoline()

XMLWordPrintable

      I got the following error message when I run a pipeline job, (pipeline script from SCM - git)

      groovy.lang.GroovyRuntimeException: Ambiguous method overloading for method java.lang.Integer#multiply.
Cannot resolve which method to invoke for [null] due to overlapping prototypes between:

       

      Here is the code:

       

      def tailFactorial
tailFactorial = { int number, BigInteger theFactorial = 1 ->
number == 1 ? theFactorial :
tailFactorial.trampoline(number - 1, number * theFactorial)
}.trampoline()
println tailFactorial(5)

       

      In "Script Console", it runs well.

      Jenkins ver. 2.60.1

      Pipeline job plugin ver: 2.12.1
