Scala for Snyk Open Source

For Scala with Snyk Open Source, the following file format is supported: build.sbt

Available features:

For sbt, Snyk provides: CLI support, SCM support, license scanning.

CLI support for Scala

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 compatible with Snyk. Use the legacy method, addSbtPlugin() instead. Snyk recommends installing the 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 information on installing sbt-dependency-graph for use with the Snyk CLI, see How to install the SBT dependency graph plugin to test Scala projects with Snyk CLI.

SCM integration support for Scala

You can import Scala sbt Projects from any of the supported Git repositories. For more information, see Organization-level integrations.

To test your Scala Projects using sbt as a package manager, Snyk analyzes your build.sbt file. To ensure that this works properly, you must have this file in your repository before importing your Projects.

You cannot declare versions of dependencies in a file that is not accessible to Snyk using a Source Code Manager (SCM) integration, for example, Dependencies.scala.

To ensure that your Scala dependencies are detected when you import your Projects using an SCM integration, your build.sbt dependencies must be declared in a format that Snyk can detect, for example: "commons-io" % "commons-io" % "2.11.0".

You can use a version declared in a variable if the variable is in the build.sbt file, for example:

  lazy val derbyVersion = "10.4.1.3"
  libraryDependencies ++= Seq(
    "org.apache.derby" % "derby" % derbyVersion
  )
