RE: [ajdt-dev] AJDT Aspect comment modification take 3 minutes to rebuil

["Sebastien Tardif" <stardif@xxxxxxxxxxxx>]

I have 46 projects in the workspace. 2 projects define aspects. A total
of 4 projects have AspectJ enabled on them.

I do not use inpath. I use aspect path when I want a project be weaved
by the aspect defined by another project.

I do not use groovy, and it was not explicitly installed.

To be able to use AJDT in the development of our software this issue and
most importantly https://bugs.eclipse.org/bugs/show_bug.cgi?id=287555
would have to be fixed or the productivity lost is too significant.

A full trace about putting a space in the JavaDoc will be sent shortly
to your private email.

Below is some extract of the full trace:

Hi Sebastian,

It does seem strange that a white space change will cause a full build
and reweave of your project.  I'd like to know a little more about
your set up:

1. How big are your projects?  How many are involved?

2. are you using inpath?  We have not spent much time optimizing for
in path usage.  If this turns out to be an issue for you, then there
are ways you can by pass this.

3. do you have the groovy plugin installed?  We are currently working
out some issues between the two plugins.  I don't think it will, but
there *might* be an issue with incremental builds if both plugins are
installed.

4. Can you open the AJDT Event trace view, in the filter select all,
and then send an attachment of the results to the list (or send to me
personally, if there is proprietary information involved)?

A whitespace change of any file should trigger a build, but the build
should finish in an unnoticeable amount of time.
