How scanning Scala projects works

To scan your dependencies, you must ensure you have first installed the relevant package manager, and that your project contains the supported manifest files.
Snyk scans Scala projects by running sbt plugins or examining your build.sbt, and compares the versions of every direct and transitive dependency in your project against Snyk's Maven vulnerability database.

Snyk CLI tool for Scala projects

The Snyk CLI uses the sbt-dependency-graph plugin which has been included in sbt as a built-in plugin since sbt 1.4.
However, the recommended method of calling the plugin in sbt 1.4+ is not currently compatible with Snyk. Use the legacy method, addSbtPlugin(), instead (see below).
You will most likely want to install sbt-dependency-graph as a global plugin so you can use it in any sbt project.
To do this, add the plugin dependency to ~/.sbt/0.13/plugins/plugins.sbt for sbt 0.13 or ~/.sbt/1.0/plugins/plugins.sbt for sbt 1.0+.
To add the plugin to a single project only, update the project/plugins.sbt of your project instead.
Regardless of which sbt version you are using, you must use the following command in the relevant plugins.sbt file:
addSbtPlugin("net.virtual-void" % "sbt-dependency-graph" % "0.10.0-RC1")
Do not use the addDependencyTreePlugin command which the sbt-dependency-graph plugin docs recommend for sbt 1.4+. This is incompatible with the Snyk CLI. use the addSbtPlugin() command as given above.
For more details on installing sbt-dependency-graph for use with the Snyk CLI, see the article "How to install the SBT dependency graph plugin to test Scala projects with Snyk CLI."

Git services for Scala projects

Scala sbt projects can be imported from any of the Git repositories Snyk supports.
To test your Scala projects using sbt as a package manager, Snyk analyzes your build.sbt file, and so you must have this file in your repository before importing.
