[play-reactivemongo] sbt publish-local suport for Scala 2.12

[Fábio Pinheiro]

Today the "Update to Scala 2.12 #226" was pull to master.

I have some questions about how to build the project for Scala 2.12 and play 2.6.0-M5, from the master branch.
If I do "sbt publish-local" it will only publish "play2-reactivemongo_2.11"

By the away in Play2-ReactiveMongo.scala you have the key crossScalaVersions two-time:
crossScalaVersions := Seq("2.11.8", "2.12.1")
crossScalaVersions := Seq(scalaVersion.value) //scalaVersion := "2.11.8"

I was trying to imitate travis-ci by:

"export PLAY_VERSION=2.6.0-M5"

diff --git a/project/Play2-ReactiveMongo.scala b/project/Play2-ReactiveMongo.scala
index 35d7513..f3098fd 100644

But I got 2 errors.

Any ideas on how to resolve?

I found a quick a workaround in http://www.scala-lang.org/news/2.12.0

Can someone please tell me what should we do to fix this problem for others in the future?

Should I open one Issue and start a branch (pull request)?

What is the correct way to fix this?

"""

SCALADOC CAN BE USED TO DOCUMENT JAVA SOURCES

This fix for SI-4826 simplifies generating comprehensive documentation for projects with both Scala and Java sources. Thank you for your contribution, Jakob Odersky!

This feature is enabled by default, but can be disabled with:

scalacOptions in (Compile, doc) += "-no-java-comments"

Some projects with very large Javadoc comments may run into a stack overflow in the Javadoc scanner, which will be fixed in 2.12.1.
