I am trying to follow along this tutorial and I can't get reactivemongo to work:

According to https://mvnrepository.com/artifact/org.reactivemongo/play2-reactivemongo.
Required scala version is 2.11 for reactivemongo 0.11.7.play24.
Try 0.13.0-play26 for scalaVersion := "2.12.4" and play 26.
libraryDependencies += "org.reactivemongo" %% "play2-reactivemongo" % "0.13.0-play26"
For my existing projects I am migrating from scalaVersion 2.10.5 to 2.11.7 and sbtVersion 1.13.9 also.
Current migrating project is Sales, it have Sales-common, Sales-read, Sales-write modules. It have one dependent project Core. But I don't have Core project code I have only already published artefact jars(I have myapp-core-read_2.10-2.2.33.jar, 2.10 is Scala version).
My project looks like this
Sales
common
build.sbt
read
build.sbt
write
build.sbt
build.sbt
Till now, with scala 2.10.5 everything working fine using in real time also.
After change the version I run sbt clean and sbt update. I am getting Unresolved dependency issue like this:

Important note: Scala 2.10 and 2.11 are not binary compatible so you will have to recompile the modules on which you depend
Answer to question:
This seems to be related to how SBT resolves dependencies. When you declare a dependency like so:
"com.mycompany" %% "myapp-core-read" % myappsales.CoreVersion
The %% part in the declaration means that SBT will automatically append the scala version to the library name, so your dependency becomes
group: com.mycompany
artifactId: myapp-core-read_2.11
version: `your version`
It seems that your myapp-core-read was not compiled with scala 2.11 thus SBT can't find the correct version.
You can avoid this by using % and applying the correct suffix manually, so your dependency would become:
"com.mycompany" % "myapp-core-read_2.10" % myappsales.CoreVersion
Having said that, I think scala 2.10 and 2.11 are not binary compatible so you might have to recompile the myapp-core-read module with 2.11.
I mentioned json4s-native 3.3.0 but it refering 3.3.0-SNAPSHOT.
In my project there is 3 modules (common, read and write) each have its scala.sbt.
Before change:
"org.json4s" %% "json4s-native" % Versions.Json4s % "compile",
After change:(Changed all the places in 3 modules)
"org.json4s" %% "json4s-native" % "3.3.0" % "compile",
I run:
sbt
clean
update

Why it still looking for SNAPSHOT version?
There's a fairly standard way of investigating this kind of problems. In your plugins.sbt
addSbtPlugin("net.virtual-void" % "sbt-dependency-graph" % "0.8.2")
Then go sbt dependencyBrowseGraph, this will open your browser and take you to a page where the entire graph of your dependencies including the evicted one can be browsed. Now figure out where the SNAPSHOT is coming from and get rid of it with an exclusion.
After adding
libraryDependencies += "org.scalatest" %% "scalatest" % "3.0.0" % "test"
to build.sbt, and refreshed the project, I got this msg.
SBT project import
[warn] Multiple dependencies with the same organization/name but
different versions. To avoid conflict, pick one version:
[warn] * org.scala-lang.modules:scala-xml_2.11:(1.0.5, 1.0.4)
Changing the above to
libraryDependencies ++= Seq(
"org.scalatest" %% "scalatest" % "3.0.0" % "test"
exclude("org.scala-lang", "scala-reflect")
exclude("org.scala-lang.modules", "scala-xml_2.11")
)
solves the issue. However, instead of excluding scala-xml_2.11 version 1.0.5 from scalatest, I would like to force the scala compiler to use scala-xml_2.11 version 1.0.5 instead of version 1.0.4. (I researched the versions at https://mvnrepository.com.) Thus I tried substituting scalaVersion := "2.11.8" for
libraryDependencies ++= Seq(
"org.scala-lang" % "scala-reflect" % "2.11.8",
"org.scala-lang.modules" % "scala-xml_2.11" % "1.0.5"
)
This however results in
SBT project import

The way to exclude specific transitive dependency is this:
Run sbt evicted to figure out which of the project dependencies is pulling in outdated library, let's assume the problematic library is: com.typesafe.slick.
Add the following exclude (the parentheses are important):
("com.typesafe" %% "slick" % "3.1.1").exclude("org.scala-lang.modules", "scala-xml_2.11")
Add this normally as you would be listing dependencies.
This will prevent sbt from including any version of scala-xml that was coming in as a transitive dependency of Slick.
Don't substitute; you need both scalaVersion and libraryDependencies.
Though use
scalaVersion := "2.11.8"
libraryDependencies ++= Seq(
"org.scala-lang" % "scala-reflect" % scalaVersion.value,
"org.scala-lang.modules" %% "scala-xml" % "1.0.5"
)
to avoid bugs when you eventually change scalaVersion.
By removing scalaVersion you get default scalaVersion := "2.10.4" (with your version/settings of SBT, at least) but your libraryDependencies still require 2.11.
I have this in my build.sbt:
libraryDependencies += "com.typesafe.akka" %% "akka-actor" % "2.4-SNAPSHOT"
libraryDependencies += "com.typesafe.akka" %% "akka-slf4j" % "2.4-SNAPSHOT"
