When executing clojure-jack-in-clj, emacs freezes for some seconds. When I hit C-g (keyboard-quit), the repl starts and the stacktrace in the *nrepl-server ...* buffer flushes (so I can read it).
Error:
java.lang.IllegalArgumentException: No implementation of method: :send of protocol: #'clojure.tools.nrepl.transport/Transport found for class: nrepl.transport.FnTransport
@bozhidar explained that this implies tools.nrepl & nrepl are both loaded (which lein deps :tree confirms), which apparently is a problem.
So I tried excluding tools.nrepl using [figwheel-sidecar "0.5.16" :exclusions [org.clojure/tools.nrepl]]. This kinda works, but then I get:
java.io.FileNotFoundException:
Could not locate clojure/tools/nrepl/middleware/interruptible_eval__init.class or
clojure/tools/nrepl/middleware/interruptible_eval.clj on classpath.
Please check that namespaces with dashes use underscores in the Clojure file name.
