---------------------------------------

             Summary: can't instantiate a class that inherits from base class marked with
@MapConstructor
                 Key: GROOVY-8760
                 URL: https://issues.apache.org/jira/browse/GROOVY-8760
             Project: Groovy
          Issue Type: Bug
          Components: groovy-runtime

         Environment: intellij 2018.1.4, java jdk 8.0_172, groovy 2.5.1

basic inheritance where parent is tagged with @MapConstructor then child class cant be instantiated

 

example as follows 

 

@MapConstructor
class A {
 String name

 A() {}

 String toString() {
 "A ($name)"
 }
}

class B extends A {
 String toString() {
 "B ($name)"
 }
}

def myA = new A(name:"will")
println myA

def myB = new B(name:"fred")
println myB

 

run this and get a RT exception 

A (will)
Caught: java.lang.NoSuchMethodError: com.softwood.scripts.A: method <init>()V not found
java.lang.NoSuchMethodError: com.softwood.scripts.A: method <init>()V not found
