------------------------------------------------------------------------
[~trohrm...@apache.org] After trying around for a while I managed to overcome
the issue. Here are the required steps
* Run the `tools/change-scala-version.sh` script
* Run `mvn clean` from the console
* Optionally, forcefully activate the `scala-2.11` profile & deactivate
`scala-2.10` from the IntelliJ Maven panel. Strictly speeking this is not
needed because after running the script the default profile is changed to
`scala-2.11`.
* In IntelliJ, click "Generate Sources and Update Folders for all Projects" in
the same panel (but maybe a simple "Reimport all Maven projects" will be enough)
* In IntelliJ, run "Build > Rebuild Project"
This worked for me on the latest IntelliJ Ultimate (14.1.5).

> 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.
