Re: [aspectj-users] Writing only weaved classes to destdir - not everything from inpath
|
Hi Matthew,
sorry for my late answer here but I just retrieved your mail.
You suggest to weave each JAR one by one and that's what I did in the end but
this isn't the best solution because I'm weaving several JARs which aren't
changed by any aspect. My problem is that I don't know exactly which JARs might
be affected by my aspect. So that I don't miss anything I weave all JARs and
redeploy those JARs.
But a better solution would be only to redeploy JARs which really changed or to
have a way to decide if a JAR might be affected before I weave. I was searching
for a way to minimize the overhead of weaving everything or a way to get the
information which JARs really changed.
After some tests I dropped the solution of binary weaving and decided to do
load-time weaving which works fine for me now ;-) Using load-time weaving I
don't have to think about the packaging of my application.
Thanks for your help,
Fabian
