-----------------------------------------
Summary: Deploy multiple Scala versions for Maven artifacts
Key: FLINK-2940
URL: https://issues.apache.org/jira/browse/FLINK-2940
Project: Flink
Issue Type: Improvement
Components: Build System
Affects Versions: 0.9, 0.10
Reporter: Maximilian Michels
Fix For: 1.0
Flink implicitly defaults to Scala 2.10 at the moment. For 0.10 we already
built Scala 2.11 artifacts but did not deploy them in the Maven repository. For
the 1.0 release, multiple Scala versions should be offered via Maven.
The artifacts which depend on a version of Scala, should contain the Scala
version in the artifact name. This is a common convention for Scala artifacts.
For example, {{flink-scala}} should be renamed to {{flink-scala_2.10}} and
there should be a {{flink-scala_2.11}} artifact as well.
Scala dependencies should be avoided where possible. For instance,
{{flink-java}} depends on Chill which depends on a specific version of Scala.
So we would have {{flink-java_2.10/11}}. We can either try to get rid of the
Scala dependency for these modules or shade our version of Scala..
