Próbuję użyć zestawu SDK IntelliJ jako samodzielnego parsera java i działa on dobrze w większości przypadków, ale nie może rozwiązać problemu z typem zwrotnym.Rozdzielczość symboli w samodzielnym parserze IntelliJ

Kiedy debugowanie resolveMethod dla verify(mock).simpleMethod() w następnej próbki wewnątrz IntelliJ:

public class ResolutionTest { 

    private interface IMethods { 
     String simpleMethod(); 
    } 

    private IMethods mock; 

    public static <T> T verify(T m) { 
     return m; 
    } 

    public void test() { 
     verify(mock).simpleMethod(); 
    } 

} 

widzę typ zwracanej verify(mock) jak IMethods i simpleMethod również rozwiązane poprawnie. Ale w moim wyniku zwracania parsera typ verify(mock) ma wartość T i simpleMethod z powodu tego niepowodzenia. Chyba nie mam żadnej usługi lub rozszerzenia, ale nie wiem, który.

i wyjście:

verify(mock).simpleMethod(); 
Resolving method verify 
ResolutionTest.verify 
Resolving method verify(mock).simpleMethod 
Resolution failed

W celu dokonania tej próbki do pracy musiałem dodać rt.jar poprzez projectEnvironment.addJarToClassPath(file); - niestety nadal jestem coraz awarii Rozwiązanie Metoda 2 w mockito i nie mogę utworzyć małej próbki, która powiela problem. Wciąż informacje o rt.jar mogą być przydatne dla kogoś, więc dodam je jako odpowiedź.

Funkcja zagadnień:

@Test 
public void any_should_be_actual_alias_to_anyObject() { 
    mock.simpleMethod((Object) null); 

    verify(mock).simpleMethod(any()); 
    verify(mock).simpleMethod(anyObject()); 
} 

Mój obecny zrozumienie problemu: dowolny() return jest nazwą rodzajową i simpleMethod ma wiele przeciążeń i rozpoznawania nazw nie mógł odebrać prawidłowego jeden, ale sama idea jest w stanie wybrać odpowiedniego wariantu .

P.S. Po ustawieniu poziomu języka Java na 6 (jak w źródłach mockito) - nie ma już żadnych awarii.
