Re: [aspectj-users] Ant task: choosing which aspect to weave

[Matthew Webster <matthew_webster@xxxxxxxxxx>]

Camila,

I assume your application is packaged as a JAR file or set of classes which
you specify on the -inpath/injars and your aspects as a JAR file which you
specify using -aspectpath. The woven application classes end up as class
files (with a destination optionally specified using -d) or a JAR file
using -outjar.

If you want to be selective about which aspects to weave with your
application you will need to put them in separate JAR files. Alternatively
a better practice is to build your aspect library using abstract aspects.
When you binary weave you select both the aspects to be woven and their
scope by compiling the necessary concrete aspects at the same time. The
concrete aspects are then packaged with the application.

      <target name="weave">
            <iajc srcdir="${basedir}/src"
                  includes="**/MyConcreteAspect.aj"
                  aspectpath="${basedir}aspects.jar"
                  injars="${basedir}/application.jar"
                  classpath="${aspectjrt}"
                  outjar="${basedir}/woven-application.jar"
                  verbose="true"
            />
      </target>

Subject:    [aspectj-users] Ant task: choosing which aspect to weave


Hello,

Here I am again fighting with Ant.
The older problem was solved, thanks Adrian and Wes. The jar file is
created.
But now I have another problem: I have a jar file with .class aspects,
but I don't want all of them to be weaved into my code. I want to
choose which aspects will be weaved.
Is there a way of doing this, using something like <exclude>? What
about command-line compiler?
I've tried, but I am a dummy in Ant, so... It'm in trouble.

Thanks,
