Marcin Zajaczkowski commented on GROOVY-10196:
----------------------------------------------
Btw, maybe it will make it easier to find a culprit. It is a regression in
Groovy 3.0.7. With 3.0.6 (and 3.0.4) it works fine.
> "Cannot find matching method" with specific class hierarchy and static
> compilation

> Reporter: Marcin Zajaczkowski
> Assignee: Eric Milles
> Priority: Minor

> /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

> {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> {

> 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
