How to fix WARNING: clj-refactor and refactor-nrepl are out of sync? - clojure-maven-plugin

Question

I'm using clojure-maven-plugin. When I do a cider-connect I get this "WARNING: clj-refactor and refactor-nrepl are out of sync. Their versions are 2.4.0-SNAPSHOT (package: 20171117.317) and n/a, respectively." Is there anything I can do to my pom.xml to make this warning go away? I've tried adding refactor-nrepl 2.4.0-SNAPSHOT as a dependency.

Answer 1

I have an older project that uses maven to build for reasons and this configuration worked for me:
Make sure you have all the needed dependencies in place.
<dependencies>
<dependency>
<groupId>nrepl</groupId>
<artifactId>nrepl</artifactId>
</dependency>
<dependency>
<groupId>cider</groupId>
<artifactId>cider-nrepl</artifactId>
</dependency>
<dependency>
<groupId>refactor-nrepl</groupId>
<artifactId>refactor-nrepl</artifactId>
</dependency>
</dependencies>
Then configure the middleware in the plugin config.
<plugin>
<groupId>com.theoryinpractise</groupId>
<artifactId>clojure-maven-plugin</artifactId>
<version>${clojure-maven-plugin-version}</version>
<extensions>true</extensions>
<configuration>
...

Cider-connect needs some dependencies (cider and clj-refactor nrepl-middleware).
The following links explain how to add the dependencies for boot or lein.
https://github.com/clojure-emacs/refactor-nrepl
http://cider.readthedocs.io/en/latest/installation/#ciders-nrepl-middleware
Example boot: .boot/profile.boot
(require 'boot.repl)
(swap! boot.repl/*default-dependencies*
concat '[[cider/cider-nrepl "0.15.1"]
[refactor-nrepl "2.3.1"]])
(swap! boot.repl/*default-middleware*
concat '[cider.nrepl/cider-middleware
refactor-nrepl.middleware/wrap-refactor])
