RE: [ajdt-dev] Re: Slow Build and Clean Times ... Where To Start?

Matt,

Tell me if this makes any sense.  I removed the structure options from our
AspectJ projects and then cleaned/built.  It took about 20minutes.  So then
I turned it back on and clean/built again.  It still took 20 minutes.  Is
there anywhere that could cache those setting that isn't getting cleaned
out.  I've rebuilt about 5 times since then and it consistently takes 20
minutes.

Yes, the last field of the version is a date/timestamp, so that build is
from 5 Oct, prior to 1.2.0M1. But I'm fairly sure that it has the build time
classpath resolver in it, making bug 70000 not relevant here. I'm not
specifically aware of any changes since then that might affect you, but if
you want to upgrade, the latest development builds should be okay. The
development update site is: 
http://download.eclipse.org/technology/ajdt/30/dev/update 

It would also be useful to know the number of lines of code you have, to see
if we can scale up the measurements I made on a smaller project, as reported
in bug 44215. A 512m heap sounds too small to me, for a project that big. If
you have the available physical ram, I suggest increasing the heap to see if
that makes the build any faster.

Regards,

Matt.
