Kudu drivers for scala 2.12

Question

Are there any Apache Kudu drivers for Scala 2.12? And if not, are they planned?

And if not, is this a warning sign that Apache Kudu is not going to be developed any more?

I am able to work with Kudu from Spark 2.4 and Scala 2.11, but I would prefer to migrate to Scala 2.12

  , "org.apache.kudu" % "kudu-client" % "1.6.0-cdh5.14.4"
  // At this time, the Kudu libraries are only available for Scala 2.11
  , "org.apache.kudu" %% "kudu-spark2" % "1.4.0" excludeAll(
    ExclusionRule(organization = "org.apache.kudu", name = "kudu-client")
  )

There is an email by Grant Henke, which explains how to build it on your own (for now, it's not published):

I filed KUDU-3128 https://issues.apache.org/jira/browse/KUDU-3128 to track adjusting the build to also compile and publish a 2.12 version of kudu-spark.

For now you should be able to build your own by updating the Spark version in dependencies.gradle: https://github.com/apache/kudu/blob/master/java/gradle/dependencies.gradle#L55

To build the Jar, in the java directory, run :
*./gradlew :kudu-spark:assemble*

You can also run all the tests with:
*./gradlew :kudu-spark:test*

The jar can then be found at:

*./kudu-spark/build/libs/kudu-spark2_2.12-{version}.jar*

As for the future, I guess you can subscribe to the mailing list and ask.
