> NAR Plugin incorrectly handling controller service API with inheritance

>                 Key: NIFI-10253
>                 URL: https://issues.apache.org/jira/browse/NIFI-10253
>             Project: Apache NiFi
>          Issue Type: Bug
>    Affects Versions: nifi-nar-maven-plugin-1.3.4
>            Reporter: Bryan Bende
>            Assignee: Bryan Bende
>            Priority: Major

> In a previous issue NIFI-10011, we fixed an issue where a controller service 
> implementation may have inheritance and one of the super classes may be the 
> one that implements the API.
> This is a similar issue, but on the API side. If the API has multiple 
> interfaces involved, we need the manifest to say that an implementation 
> satisfies all of these interfaces, and currently its only getting the lowest 
> level.
> Example...
> API:
> {code:java}
> AtomicDistributedMapCacheClient<R> extends DistributedMapCacheClient {code}
> Implementation:
> {code:java}
> RedisDistributedMapCacheClient {code}
> The manifest contains:
> {code:java}
> "providedApiImplementations" : [ {
>           "group" : "org.apache.nifi",
>           "artifact" : "nifi-standard-services-api-nar",
>           "version" : "1.17.0-SNAPSHOT",
>           "type" : 
> "org.apache.nifi.distributed.cache.client.AtomicDistributedMapCacheClient"
>         } ], {code}
> The provided API implementations should contain the atomic DMC and regular 
> DMC, since technically it implements both.
