This will give you a link to a web-based report, where you can find <<viewing_debugging_dependencies.adoc#sec:debugging-build-scans,dependency information>> like this:

Gradle takes care of specifying a compatible version of `scala-library` for you.

You can diagnose problems with the version of the Zinc compiler selected by running <<viewing_debugging_dependencies.adoc#sec:debugging-build-scans,dependencyInsight>> for the `zinc` configuration.

This makes the dependency declarations in your build script and the <<viewing_debugging_dependencies.adoc#sec:identifying_reason_dependency_selection,dependency insight report>> easier to interpret.

This task is similar to the `dependencyInsight` <<viewing_debugging_dependencies.adoc#sec:identifying_reason_dependency_selection,reporting task>>.

By default, `outgoingVariants` prints information about all variants.
