add more projects

[SethTisue]

(I edit this list frequently. except when I forget to update it at all.)

projects we'd like to include:

• high priority:
  • Spark add Spark #763 — volunteers needed
  • (nothing else right now?)
• would be nice:
  • scastie (not a lib, but good to have some apps)
  • Play sample repos (we do have play-webgoat)
  • macwire
  • hamsters
  • squants (PR)
  • algebird
  • thyme
  • metal
  • scalatra
  • finagle
  • ammonite (problematic because it's built with mill now, not sbt; someone would need to make a minimal sbt build; or perhaps someday dbuild will support mill)

what won't we add? important to ecosystem but probably out of scope here: Dotty, IntelliJ, Scala Native, cbt (builds itself, not built by sbt), mill (ditto, they have an sbt build at the moment but plan to eliminate it), all sbt plugins (there could be a separate build for that), ...

we might look at https://github.com/olafurpg/scala-experiments for candidate additions. also the Dotty community build

closing. this ticket has served its purpose; the build is now big enough, overall. we'll still add specific things from time to time, but there's no point to keeping this neglected ticket open.
