Groovy code cannot find Java constructor

Question

When I run the main method in the Groovy code below, I get a groovy.lang.GroovyRuntimeException: Could not find matching constructor for: com.example.Person(java.lang.String, com.example.Pet). Why is that? I'm using the latest version of the Groovy/Grails Tool Suite.

Groovy:

package com.example

import groovy.transform.TypeChecked

@TypeChecked
class Test {
    static main(args) {
        Pet fido = new Pet(name: 'Fido', nickname: 'Scruffy')
        Person dave = new Person('Dave', fido)
    }
}

@TypeChecked
class Pet {
    String name
    String nickname
}

Java:

package com.example;

public class Person {
    private String name;
    private Pet pet;

    public Person(String name, Pet pet) {
        this.name = name;
        this.pet = pet;
    }
}

Make sure you compile and run in this order:

• groovyc Pet.groovy
• javac Person.java

• groovyc Test.groovy

• groovy Test

It works for me as expected if the above order is followed. In GGTS make sure you are compiling/building the project as expected to make sure dependent classes are built.
