Jens Bannmann commented on MCOMPILER-205:
-----------------------------------------
[~rfscholte], could you please clarify and expand on the following comment?
{quote}The reason is that the default java compiler is quite fast, likely much
faster than analyzing per file what to do with it.

It seems that despite that comment and my attempt at explaining everything in
the SO answer [~Didier Loiseau] kindly linked, there is still confusion, as
some added the following comment ("the developer" and "he" referring to
[~rfscholte]):
{quote}I think you have misread the developers comment. I was scratching my
head at first but I think what he meant was that the default incremental
compilation provided by javac is fast. I very much doubt he meant that
recompiling everything each time you make a change is preferable. You only need
a project of >100 source-files to show that's nonsense.
