Marcin Zajaczkowski created GROOVY-10196:
--------------------------------------------
Summary: "Cannot find matching method" with specific class
hierarchy and static compilation
Key: GROOVY-10196
URL: https://issues.apache.org/jira/browse/GROOVY-10196
Project: Groovy
Issue Type: Improvement
Components: Static compilation
Affects Versions: 3.0.8
Reporter: Marcin Zajaczkowski
Groovy static compilation reports:
{code:java}
> Task :compileTestGroovy
startup failed:
/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, bu I report
it as I encountered it in the class hierarchy available related to
LinkedMultiValueMap in Spring Framework (classes originally in Java).
Reproduced with Groovy 3.0.8
