IAuthenticationProvider is deprecated in microsoft-graph:2.3.0, how do I create a GraphServiceClient instance now?

Question

I am upgrading the version of the msgraph-sdk-java library in my project. I was using version 1.7.1 but I had some issues with setting conflict behavior when uploading files >4MB. I saw the issue was fixed in the latest version (see here) so I am trying to upgrade to version 2.3.0.

I updated my build.gradle file and noticed that now the interface IAuthenticationProvider is deprecated.

Provides authentication for a requests before it is sent by an HTTP provider.

@deprecated use ICoreAuthenticationProvider instead

It says I should use ICoreAuthenticationProvider instead but how do I build a new instance of GraphServiceClient without implementing the IAuthenticationProvider interface?

this.graphClient = GraphServiceClient.builder()
                .authenticationProvider(appAuthProvider)
                .buildClient();

Also, in the README of the library, it says we SHOULD use IAuthenticationProvider, which is even more confusing:

Answer 1

Just use whatever implementation you would have.

Whilst it is deprecated, it still works for now.

I imagine an update will allow the ICoreAuthenticationProvider to be used in the GraphServiceClient constructor, but that's not present yet.
