Play production environment generation throws warnings

Every time I run dist to generate the production environment I get the following warnings:

[warn] Scala version was updated by one of library dependencies:

[warn] * org.scala-lang:scala-compiler:2.11.0 -> 2.11.8

[warn] To force scalaVersion, add the following:

[warn] ivyScala := ivyScala.value map { _.copy(overrideScalaVersion = true) }

[warn] Run 'evicted' to see detailed eviction warnings

Now, in build.sbt I have the following line:

scalaVersion := "2.11.12"

I changed it from "2.11.8" when I installed a cats library as the installation said that Scala version was migrated to 2.11.12.

Should I ignore the dist message?

The problem is described here: Github sbt

The issue is still open.

It proposes:

Reflecting the scalaVersion mediator, we could issue a warning like:

[warn] Some library dependencies use a newer Scala version than this project: 
[warn]  * org.scala-lang:scala-library:2.12.0 -> 2.12.1 
[warn] We recommend you upgrade to the latest scalaVersion patch: 
[warn]  scalaVersion := 2.12.1 if we know that the mediator is turned on.
