             Summary: Hardcode scala.version to 2.11 in flink-quickstart-scala
                 Key: FLINK-7414
             Project: Flink
          Issue Type: Improvement
          Components: Build System
    Affects Versions: 1.4.0
            Reporter: Aljoscha Krettek
            Assignee: Aljoscha Krettek
            Priority: Blocker
             Fix For: 1.4.0

Currently, the {{scala.binary.version}} of the Scala Quickstart is derived from 
the {{scala.binary.version}} of Flink at the time when the Quickstart is built. 
This means that whatever Scala version is active when we push the Quickstart 
takes precedence. Currently, when deploying SNAPSHOT versions we deploy 2.10 
first, then 2.11, i.e. the 1.4-SNAPSHOT Scala Quickstart has Scala version 
2.11. The release script deploys first 2.11 and then 2.10, meaning the final 
1.4.0 Scala Quickstart would have 2.10.

Simply fixing it to the latest supported (by Flink) will circumvent that issue 
and users can easily change the Scala version in the Quickstart.
