@dsowerby Re. Set<T> haven't tried it myself but ran into a similar issue with Dagger2 -- Set<T> in Kotlin is covariant on T i.e. it is actually equivalent to Set<? extends T> in java (since a Kotlin Set is read-only). Try changing it to MutableSet<T> which is equivalent to the invariant java Set<T>, and see if Guice can inject it then.
