Subject [jira] [Comment Edited] (FLINK-2858) Cannot build Flink Scala 2.11 with IntelliJ

[~trohrmann@apache.org] After trying around for a while I managed to overcome the issue. Here
are the 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).

> 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.
