Coming from Maven, where the plugin exports all kinds of configuration variables to the Jenkins environment variables, I really miss this feature with SBT.
It is a really convenient feature, which especially comes into play when a Jenkins job contains extra tasks based on the output of the SBT task (code analysis, task scanning etc.).

Personally I would like to see (read: need):

• Scala version
• Application version
• Application name
• Organization

There are probably more, but these are the ones I miss the most.
