To be able to test scala projects, you need to use the sbt-dependency-graph plugin for sbt. To read more about sbt-dependency-graph, go here: https://github.com/jrudolph/sbt-dependency-graph
We recommend that you install it as a global plugin, although it can be installed by project as well.
Install sbt here: https://www.scala-sbt.org/1.x/docs/Setup.html
Using sbt plugins: https://www.scala-sbt.org/0.13/docs/Using-Plugins.html
NOTE: Upon initial install of sbt, the ~./sbt/<version>/plugins/plugins.sbt file and folder will not exist, you will have to create it.
The ~./sbt/<version>/plugins/plugins.sbt file should be updated with the following line:
addSbtPlugin("net.virtual-void" % "sbt-dependency-graph" % "0.9.2")
