WARNING: CIDER requires cider-nrepl to be fully fuctional. Many things will not work without it!

Nobody has claimed this yet.

Hello~ I'm using luminus framework with +re-frame +postgres.

I also use emacs with cider.

The step through the warning is like this :

in terminal:
```
lein run
```
```
lein figwheel
```
and then in emacs:
```
M-x cider-connect localhost 7002
```
now I got this warning messages in repl
```
WARNING: CIDER requires cider-nrepl to be fully fuctional. Many things will not work without it!
More information.
WARNING: clj-refactor and refactor-nrepl are out of sync.
Their versions are 2.4.0 (package: 20180826.2149) and n/a, respectively.
You can mute this warning by changing cljr-suppress-middleware-warnings.
```

This is just WARNING so I don't have crucial problem with that, but I wanted to jump to the source code with ``key but I couldn't.
The reason I guess is the first warning message and I tried to add the cider-nrepl as many as possible but I still get the same warning message.
I guess something's wrong with port 7002(figwheel), it might not compatiable with cider-nrepl.

I'm not really sure this is the right place to ask but I wonder somehow you can answer me!

I'm adding my `project.clj` and `profiles.clj`(located in ~/.lein/)

Start with project.clj and profiles.clj, focusing on the CIDER, refactor-nrepl, Piggieback, Figwheel, and nREPL configuration around port 7002. Reproduce the connection using lein run, lein figwheel, and M-x cider-connect, then determine whether the warnings and failed M-. behavior are resolved.
