RE: [ajdt-dev] AJDT speed with multiple projects
|
Thanks for your prompt response.
In the log we have provided, we added only a space so all the dependent
did incremental build, but when we add or remove a constant the
dependent do full build. We only use one output location for each
project but they have different names and we use special project type
Web, EAR, EJB module so they may add implicit output location or mix-up
the logic.
Like you said, we are probably impacted by
https://bugs.eclipse.org/bugs/show_bug.cgi?id=166580

We actually have a mix, because we wanted to minimize the overhead of
AJDT so we have excluded the projects we think are unlikely to need to
be woven.
Is it always a problem to mix the project types? Do we have a precise
description somewhere of the combination having or not the problem?

Indeed - but I didn't think anything had gone in that would affect you
during that time. And from the query I just ran to see what was fixed
in that time:

only one thing struck me as a possible fix you didn't have:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=166580
which is to do with incremental builds always being full builds when
using multiple output locations. But as your information said every
build that did occur was incremental, I don't think this is affecting
you.

Do you have any java projects or are they all AspectJ projects? If you
have a mixture, you might well be hitting what I recently described in
another thread last week.

Of course.

I had a quick look over the AJDT bugs and I can't see one.

This can be the case if Java/AJ projects are mixed. If it isn't that
then it sounds like a bug.

I do believe I have a bug open for that somewhere - and am looking at
memory usage when I get a chance.
