Support sbt projects

[albuch]

Hey,
it would be awesome to support sbt dependencies and plugin dependencies as well.

https://www.scala-sbt.org/1.x/docs/Library-Dependencies.html
https://www.scala-sbt.org/1.x/docs/Using-Plugins.html

Multi-projects are supported in sbt as well and is a common use case so that should be considered as well: https://www.scala-sbt.org/1.x/docs/Multi-Project.html

Totally up for this. I've got some work to do getting Maven support out of beta first, but once that's done sbt support would be a great addition.

My company is working with scala, once support for Gitlab and sbt is there I'd be happy to become a paying customer of dependabot.

Thanks @tyrcho. I'm still really keen on adding both - will keep you posted.

I ran into this sbt plugin which should help a lot !

You can append addSbtPlugin("com.timushev.sbt" % "sbt-updates" % "0.3.4") to the end of project/plugins.sbt (creating it if not present) and then run sbt dependencyUpdates and parse the output in stdout. It looks like that:

[info] Found 10 dependency updates for notification-impl
[info]   com.datadoghq:dd-java-agent:dd-java-agent            : 0.10.0           -> 0.16.0
[info]   com.lightbend.lagom:lagom-logback                    : 1.4.6  -> 1.4.8           
[info]   com.lightbend.lagom:lagom-reloadable-server:dev-mode : 1.4.6  -> 1.4.8           
[info]   com.lightbend.lagom:lagom-scaladsl-dev-mode          : 1.4.6  -> 1.4.8           
[info]   com.lightbend.lagom:lagom-scaladsl-server            : 1.4.6  -> 1.4.8          

Note that in multi-project build you will have duplicated lines.

Even partial support for sbt in dependabot would be great (ie creating the PR to notify the library has been updated). It will probably be impossible to cover all ways in which versions are defined in sbt since you can code in your build files.

A project by @fthomas already does this. Hope you could maybe setup some sort of collaboration !
