--------------------------------------
Summary: Support cross-building with Scala 2.11
Key: SPARK-2040
URL: https://issues.apache.org/jira/browse/SPARK-2040
Project: Spark
Issue Type: Improvement
Components: Build, Spark Core
Reporter: Patrick Wendell
Assignee: Prashant Sharma
Since Scala 2.10/2.11 are source compatible, we should be able to cross build
for both versions. From what I understand there are basically three things we
need to figure out:
1. Have a two versions of our dependency graph, one that uses 2.11 dependencies
and the other that uses 2.10 dependencies.
2. Figure out how to publish different poms for 2.10 and 2.11.
I think (1) can be accomplished by having a scala 2.11 profile. (2) isn't
really well supported by Maven since published pom's aren't generated
dynamically. But we can probably script around it to make it work. I've done
some initial sanity checks with a simple build here:
