This question is related to this one — however, due to the deprecation of compile in favor of implementation, it doesn’t work. It does pick up dependencies that are declared with compile. However, with it being deprecated, using it isn’t an option (and we’d be right back here when it’s removed anyway) I got this Gradle task: And there’s just
Why LiveData setValue or PostValue triggers onChange just once in the view?

I’m trying to communicate with a Rest service that returns a simple JSON array of ints, e.g. I have the following code to make the call via WebClient: However, Spring returns me an empty Flux.
