Hi Raymond,

Thanks for your reply.
Actually I have two <javac> task in my build.xml. First <javac> task would 
compile everything from src dir "Adir" and jar it. Second <javac> task 
will compile a few java file from "Bdir" which could override some of 
first ones and create another jar again. If I put a delete task before 
second javac task, I would need to selectively delete some java classes 
instead of deleting the whole output directory which is a little bit 
complex :-). It would be nice if there is some other options to do this. 
I tried using "touch" java source before second <javac>. It works but it 
changes the source code modified time which is not desirable.

Regards,

RE: how to force recompile everything using javac task






I'd have to go with the previous recommendations on this topic and say
that wiping *.class files would be the easiest solution here.

However, if there are other restrictions such as class files in the same
directory that can't be stripped because it was a packaged class or
whatever, well....that's a little worse. But this appears to be the most
common solution to this issue.

Cheers,

Raymond

Hi,

how to force recompile everything using javac task?
Javac task always compare modify time with target classes. I want to 
recompile java source no matter target classes exists and newer.

Is there any options to achieve this?

Thanks,
