[aspectj-users] Re: [aspectj-dev] incrimental compilation

[Nicholas Lesiecki <ndlesiecki@xxxxxxxxx>]

Ok, admittedly iajc will not (in 1.1) behave like javac.

Does anyone have any good examples of how to recreate the desired behavior
(fast compiles)? In other words, do you launch one ant script and leave it
idling while launching another to do post-processing, packaging, and
deployment? How does the second script know when the first is done with an
incremental compile? Has anyone done this and relied upon it for their main
build?

The reason I'm asking: VMS (my company) just introduced AspectJ to the
project this week and the main complaint is slow incremental compiles during
the compile-deploy-test cycle.

If we manage to figure it out before someone assists, I'll post the solution
here. 

Cheers,
Nick
