clean project in flash builder on debug launch

Using Flash builder 4 to build an AIR app.

I keep having my code changes not take effect when I launch开发者_StackOverflow社区 the project with the debugger, probably happens about once an hour. So does anyone know how to have FlashBuilder clean the project automatically before each launch?

Thanks

I'm having a similar issue with a Flex application. If I make a change to an .as file the change is not taking effect. The component is being instantiated by a parent component in the application so the compiler should be catching any changes I made. In fact, I can put a syntax error in the file and it won't report a problem. I've uninstalled and reinstall Flash Builder 4. I have to do a clean every time. I tried the tip from rakslice's comment of compiling with mxmlc manually and it successfully compiled without any clues as to what the issue with incremental compiling in Flash Builder 4 is. I finally added "-incremental=false" to my project's additional compiler arguments. This takes longer to compile of course, but I find it easier than having to click Project --> Clean every time.

I find that as long as I don't change code and/or recompile while an active debug sessions is on-going; I have no issues with the application not picking up code changes between subsequent runs.

I'm finding that I have a very similar problem. Everytime I launch my Flex app in a browser I have to perform a Clean just to get it to run.

I have noticed that I get a JavaScript error saying 'swfobject' is undefined odd error to be getting.

Not sure if that helps?
