Yes, the old project is no more. Refer to https://metaredux.com/posts/2018/10/29/nrepl-redux.html for more details. All projects should adopt the new package, as the main tooling already switched to it and tools like CIDER will just drop support for the old package very soon.

That's a simply way of supporting both versions https://github.com/clojure-emacs/cider-nrepl/blob/master/src/cider/nrepl.clj#L11

@cbcoutinho Those bugs you refer to (which are the same bug actually) are unrelated to the need for updating the nREPL dep for ultra and similar packages.

We'll need greglook/whidbey#26 to go in first as otherwise Ultra will be on nREPL and our deps will be on clojure.tools.nrepl.

Is this issue resolved yet?

As far as I can tell it was fixed in whidbey 2.0.0 but older dependency is still used in ultra 0.5.4

Thanks

Trying to migrate to whidby 2.0.0 results with:

clojure.lang.Compiler$CompilerException: java.lang.RuntimeException: Unable to resolve var: whidbey.repl/printer in this context, compiling:(ultra/colorscheme.clj:62:5)

Looks like this is a breaking change
