Suggested by @alexy (I think) at nescala.

steps

Currently proxy repository requires -Dsbt.override.build.repos=true.

problem

One needs to remember to call sbt with the flag.

expectation

Provide some way of always using repositories.

• would environment variable work?
• some other file name such as ~/.sbt/repositories_force?
