Add deploy version filter to build.sh

[danslapman]

Extra condition to disable double artifact publishing and travis crashes

This should not be necessary, the sbt plugin will make sure that the sbt build exits / aborts when a release build is running and the UseForPublishing flag is false (https://github.com/scala/scala-continuations/blob/master/build.sbt#L10-L20)

@lrytz I added this because when You push a tag crossScalaVersions are overriden by build.sh. This causes crash in travis because both jdk6 & jdk8 are used un travis: https://github.com/scala/scala-continuations/blob/master/.travis.yml#L17-L18

@lrytz problem's here https://travis-ci.org/scala/scala-continuations/builds/224276366

Yes, that part i still need to fix, i'm aware of it. instead of overwriting crossScalaVersions, the script should overwrite scalaVersionsByJvm. But we need to also know the JVM version, so the tags need another #N. I'm working on this, I'll also push it here once it's ready.

[danslapman]

@lrytz I think adding another #N is more ugly than filtering jdk version somehow

[danslapman]

2.11.x releases always need to be published under jdk6 to ensure compatibility & 2.12.x releases simply can't be built on jdk6

[lrytz]

Agree it's more ugly, but also more future-proof. We might not always have a clear distinction, maybe you want to build something on JDK 9 at some point. Anyway it's not a feature for users, just for the maintainers, and it's not that hard to understand either.

[danslapman]

@lrytz sounds reasonable
