I ran into the same issue. Instead of adding new repositories you can add the dependency of Jake Wharton's library:

    .baseUrl("https://api.example.com")
    .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
    .build();

The fact that adapter has version 2.. does not mean that it is intended for use with RxJava 2, as I thought.

implementation 'com.squareup.retrofit2:adapter-rxjava2:2.1.0'
