Jackson version is too old

Question

I have the following build.sbt file:

name := \"myProject\"

version := \"1.0\"

scalaVersion := \"2.11.8\"

javaOptions ++= Seq(\"-Xms512M\", \"         


        

Answer 1

jackson-core and jackson-databind versions should match (at least up to the minor version, I believe).

So remove the dependencyOverrides and have

libraryDependencies ++= Seq(
  ...
  "com.fasterxml.jackson.core" % "jackson-databind" % "2.8.1"
)

Or specify both in dependencyOverrides

dependencyOverrides ++= Set(
  "com.fasterxml.jackson.core" % "jackson-core" % "2.8.1"
  "com.fasterxml.jackson.core" % "jackson-databind" % "2.8.1"
)

Though I'm not sure I understand what you are trying to do; the linked question seems to say that you should used an older version (2.4.4).
