Support Scala2.12+

[2efPer]

Can we support scala2.12+?

I added scala 2.12 build support in this branch

You can build using scala-2.12 profile:

mvn -P scala-2.12 clean package -DskipTests

or with make:

make package MVN_EXTRA_OPTS="-P scala-2.12"

Also changed Travis script to run tests both for scala 2.11 (default version in pom.xml) an for scala 2.12.

The artifacts are not yet published to Maven central, I will ask @gkorland to deploy it.

It seems like the approach of using maven profiles for cross compiling different scala versions doesn't work.
I tested the published Sonatype artifact and getting error both with sbt and maven.

SBT error:

[error] sbt.librarymanagement.ResolveException: unresolved dependency: com.redislabs#spark-redis_2.12;2.4.1-SNAPSHOT: java.text.ParseException: inconsistent module descriptor file found in 'https://oss.sonatype.org/content/repositories/snapshots/com/redislabs/spark-redis_2.12/2.4.1-SNAPSHOT/spark-redis_2.12-2.4.1-20190909.083112-1.pom': bad module name: expected='spark-redis_2.12' found='spark-redis_2.11';

Typically SBT used for cross compiling and it appears to be not very common with maven.

We may want to consider the following appraoches:

• using maven plugin https://github.com/Stratio/scala-cross-build-maven-plugin
• script to replace scala version in pom file, similar to Spark project, https://spark.apache.org/docs/latest/building-spark.html#change-scala-version

Hey!
Are you going to fix it in the next release? And if so, when it's planned to come?
I mean published version with Scala 2.12+ support

Hi Anton,
No estimates for this yet.

[anton-antonenko]

Ok, np 🙂
Thanks for the quick response

Hi,
Since spark-redis connector doesn't support scala 2.12+ I cant upgrade to new spark version 2.4.5 (spark 2.4.5 runs on Scala 2.12+).
Appreciate if you could publish new version.
