I am trying to automate CI/CD of a small Scala project using CircleCI. The project is built using sbt, and tested using the ScalaTest library.
As per the ScalaTest installation instruction's recommendation, I am using the SuperSafe compiler plugin, which required me to add a resolver to global file ~/.sbt/1.0/global.sbt:
resolvers += "Artima Maven Repository" at "http://repo.artima.com/releases"
I can successfully compile and test my project locally. however on CircleCI the build fails with error:

This error is to be expected when the required resolver hasn't been added in SBT -- see e.g. this issue. I am new to CircleCI and don't know where its SBT globals dir would be located, or how to modify the file.
Instead I've tried to add the resolver to my project's ./project/plugins.sbt file directly, but this has not fixed the issue.
The SBT and CircleCI config files look as follows:
./build.sbt
name := "my-project-name"
version := "0.1"
scalaVersion := "2.12.8"
libraryDependencies += "org.scalactic" %% "scalactic" % "3.0.8"
libraryDependencies += "org.scalatest" %% "scalatest" % "3.0.8" % "test"
./project/build.properties
sbt.version = 1.2.8
./project/plugins.sbt
resolvers += "Artima Maven Repository" at "http://repo.artima.com/releases"
addSbtPlugin("com.artima.supersafe" % "sbtplugin" % "1.1.7")
./.circleci/config.yml

I want a successful CircleCI build, which will require a way to add the resolver, either in the project's own files or declaring it in the SBT globals file of the CircleCI container.
Consider open issue SBT isn't using resolvers defined in project/plugins.sbt #4103. Try scoping the resolver to ThisBuild and put it in both build.sbt and plugins.sbt like so:
// someApp/build.sbt
resolvers in ThisBuild += "Artima Maven Repository" at "http://repo.artima.com/releases"
and
// someApp/project/plugins.sbt
resolvers in ThisBuild += "Artima Maven Repository" at "http://repo.artima.com/releases"
addSbtPlugin("com.artima.supersafe" % "sbtplugin" % "1.1.7")
This seems to have worked on this example repo
