Hi Ian,
Firstly, for questions relating to using AspectJ in Eclipse, the
eclipse.technology.ajdt newsgroup would be the most appropriate, which I'm
cross-posting to as this topic is probably of interest there.
For questions related to the AspectJ language itself and its use, the
aspectj-users mailing list would be best - it's much less quiet there! See
the URL below for more information:
https://dev.eclipse.org/mailman/listinfo/aspectj-users
Now, what you are trying to do is possible, by using the AspectPath
setting. For some good background info on this, and how it relates to the
InPath and classpath settings, see Adrian's blog entry here:
http://www.aspectprogrammer.org/blogs/adrian/2004/10/three_p aths_sta.html
If you right-click on project foo and select Properties > AspectJ, and
enter something like foo.jar in the output jar field, the class files from
this project will then go into that jar, instead of the bin directory. You
can then go to Property > AspectJ AspectPath of project foo.test and add
foo.jar from project foo.
To confirm what is being woven, you can turn on the following option:
AspectJ Compiler > Other > Output weaving messages to problem view.
As an aside, it seems to me that it would be more natural to be able to
specify the bin directory on the aspectpath, to avoid having to create the
output jar, but this is not currently supported by the compiler. This has
come up before, but I couldn't find it captured in a bug report, so I've
raised one now:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=84122
Regards,
Matt.
