Alexander Alexandrov commented on FLINK-2858:
---------------------------------------------
I think that the current build description in the docs does not properly
reflect what needs to be done.
All you need to do is run the `tools/change-scala-version.sh` script, the
default Scala profile is then automatically changed.
I tried to update this in [PR 1260|https://github.com/apache/flink/pull/1260].
> Cannot build Flink Scala 2.11 with IntelliJ
> -------------------------------------------
>
> Key: FLINK-2858
> URL: https://issues.apache.org/jira/browse/FLINK-2858
> Project: Flink
> Issue Type: Bug
> Components: Build System
> Affects Versions: 0.10
> Reporter: Till Rohrmann
>
> If I activate the scala-2.11 profile from within IntelliJ (and thus
> deactivate the scala-2.10 profile) in order to build Flink with Scala 2.11,
> then Flink cannot be built. The problem is that some Scala macros cannot be
> expanded because they were compiled with the wrong version (I assume 2.10).
> This makes debugging tests with Scala 2.11 in IntelliJ impossible.
