Support for Scala 2.13.0-M5

[ennru]

Play JSON 2.7.1 is available for 2.13.0-M5.

I'm not on top of the other dependencies, yet.

@ennru Any idea how to configure cross Scala compilation per project?

[2m]

In the latest sbt the +compile will actually switch and run the compile task according to the crossScalaVersions values on the per sub-project basis.

I tried crossScalaVersions := Seq("2.13.0-M5") and then +coreProject/compile just to see how it would go and I got unresolved dependency: org.scalatest#scalatest_2.13.0-M5;3.0.5: not found.

I don't really get it since scalatest is tagged with % "test", so why is it even showing during the compilation step? Shouldn't it be during tests only? (which, to be fair, will be a trouble anyway since I would like to run those tests before publishing but at least it would make sense...)

Anyone has any idea? (mostly for compiling, I wouldn't mind releasing without testing since it's not a final Scala release yet)

[ennru]

You may use Scalatest 3.0.6-SNAP6 which is published for Scala 2.13.0-M5.

[2m]

The "unresolved dependency" is actually this sbt issue: sbt/sbt#3465

You need to set crossScalaVersions := List() on the aggregate project for a workaround.

Here is a commit that adds 2.13 cross compilation and excludes a couple of projects. The +update runs successfully on that branch.

Should be available in 2.1.0

[ennru]

Thank you, quicker turn-around than I would have expected for this!

[pauldijou]

That's because @2m did everything, which was nice 😄
