I have many, many issues with the Flex Builder compiler. I will start with this one: incremental compilation. The docs state that by default, FB compiler has incremental compilation turned on, which I don't believe in the slightest. If you run a command line build with -incremental=true, the compiler generates .cache files. FB doesn't generate anything, does it just use a different mechanism to detect changes?
I have a somewhat complex project structure, 1 Flex project with 6 supporting library projects. If I make a simple change in one of the library projects, I get a 7 minute compile time as FB goes and rebuilds everything under the sun. I have done any optimizations I can think of, including giving FB a full gig of ram in the heap, using RSLs, closing unused projects, etc. What am I missing here?
