>             Project: Groovy
>          Issue Type: Bug
>          Components: Static compilation
>    Affects Versions: 3.0.8
>            Reporter: Marcin Zajaczkowski
>            Assignee: Eric Milles
>            Priority: Minor
>             Fix For: 3.0.9

> /home/.../ReproCannotFindMethod.groovy: 11: [Static type checking] - Cannot find matching method com.example.repro.LinkedMultiValueMap3#add(java.lang.String, java.lang.String). Please check if the declared type is correct and if the method exists.
>  @ line 11, column 9.
>  map.add("foo", "bar")
>  ^
> 1 error
> {code}
> in some weird, but still valid hierarchy of classes:
>  
> {code:java}
> @CompileStatic
> class ReproCannotFindMethod {
>   static ups() {
>     LinkedMultiValueMap3<String, String> map = new LinkedMultiValueMap3<>() //fails on add()
>     // MultiValueMapAdapter3<String, String> map = new MultiValueMapAdapter3<>() //works fine with add()
>     map.add("foo", "bar")
>   }
> }
> interface Map3<K, V> {
> }
> interface MultiValueMap3<K, V> extends Map3<K, List<V>> {
>   void add(K key, V value);
> }
> class MultiValueMapAdapter3<K, V> implements MultiValueMap3<K, V> {
>   @Override
>   void add(K key, V value) {
>   }
> }
> class LinkedMultiValueMap3<K, V> extends MultiValueMapAdapter3<K, V> {
> }
> {code}
>  
> It is definitely a corner case, so it might not be worth to fix it, but I report it as I've encountered it in a class hierarchy available related to LinkedMultiValueMap in Spring Framework (classes originally in Java).
> Reproduced with Groovy 3.0.8
