It may be due to macros. When using Scala macros, you need to compile the
macro definitions separately from whatever using the macros. If src/main and
src/test are compiled together, it will not work.
But why is it differently from Jenkins? Isn't both Jenkins and Travis CI
just running the Maven build? Or does Travis CI tries to be "smart" and
actually do something stupid?
