Dependabot-core: 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.

[tyrcho]

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.

[greysteil]

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 !
https://github.com/rtimush/sbt-updates

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 !

We are already using dependabot for python and ruby, but the biggest part of our codebase is scala.
Are there any updates on scala/sbt-support?

[greysteil]

Not yet. We'd still love to add sbt support, but we're a small team and are currently focussed on scaling Dependabot so it can create automated security fixes for all GitHub repos.

I was linked here from https://dependabot.com/java/ - I would like to help beta test Java Maven support

[Grundlefleck]

The PR I raised as a starting point for sbt support (#1589) was closed without comment due to staleness. Not sure whether to interpret as a bad PR that I can improve, or lack of team capacity, or something else. I'm still willing to continue on the functionality, but would prefer to see some indication of whether I'm likely to see it ever getting merged before spending more time on it.

[hmarr]

@Grundlefleck sorry about that - I've reopened the pull request and added the "enhancement" label, which should prevent stalebot rudely closing it again.

Right now the Dependabot team is working pretty flat out on some scaling challenges and bringing more of Dependabot's features to GitHub natively, which means we've (regrettably) been neglecting dependabot-core a bit. I can't promise a timeline, but I'm hopeful we'll be able to spend more time on dependabot-core soon. When we can give it some proper attention, your SBT pull request will be top of the list.

[albuch]

There is another alternative that supports scala/sbt (among many others) in a rudimentary version: https://github.com/apps/renovate
See https://docs.renovatebot.com/modules/manager/sbt/ for docs.

[ihostage]

@albuch Renovate has a constraint for sbt projects. 😞
As @mark-dhl said, Scala Steward is a really best choice for Scala/Sbt.

[coding-bunny]

Anything I can do to make our Scala project rely on dependabot?
We have a multi-tier project that combines 4 projects into a one repo with multiple SBT build files.
