Description

When you use the @InheritConstructors to pull all the constructors of a super class into a subclass this fails to work when it is used on an Inner Class. Below is an example of code that fails with error:

groovy.lang.GroovyRuntimeException: Could not find matching constructor for: D$F(D, java.lang.Integer)

when you would expect it to run.

import groovy.transform.InheritConstructors

class A {
    def arg
    A(int arg) {this.arg=arg}
}

@InheritConstructors //add it here just in case that worked!
class D {
    class E extends A {
        E(int arg) {super(arg)}
    }
    @InheritConstructors //this should make class F identical to class E
    class F extends A{}
   
    public test() {
        def test1=new E(1) //Works FINE.
        println test1.arg  // prints 1 as expected  
        def test2=new F(1) //throws GroovyRuntimeException here due to missing constructor.
        println test2.arg
    }
}

def test3=new D()
test3.test()
