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

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.

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>
          ...
          <nreplMiddlewares>
