Re: [scala] how to stop recompile all scala files even there is no file has been changed?

I don't see "all files being recompiled," only the changed ones in fact.  The changed ones are rescanned, which does take time indeed.  Like in times of Fortran, Scala compile is a good time to meditate on your algorithms and the state of the world in general -- thinking through your program in your mind eliminates extra "test by compile" cycles!

Cheers,
