Build ouptut:

# Executing command line:
/usr/lib/jvm/java-7-oracle/bin/java

/home/travis/.sbt/launchers/0.13.0-RC5/sbt-launch.jar
warn
"set javaHome in ThisBuild := Some(file("/usr/lib/jvm/java-7-oracle"))"
info
++TRAVIS_SCALA_VERSION
test

Any idea why travis is injecting the warn and the info parameters?
