    You can use $SBT_OPTS to pass additional JVM options to SBT:
       SBT_OPTS="-XX:+CMSClassUnloadingEnabled -XX:MaxPermSize=256M"

    This formula uses the standard Lightbend sbt launcher script.
    Project specific options should be placed in .sbtopts in the root of your project.
    Global settings should be placed in #{etc}/sbtopts
