cross-project aspects? [message #62304]

Hi,
Should it be possible to define an Aspect in one project which weaves
into code from another?

For example, I create an AspectJ project A. I convert an existing Java
project, B, by right-clicking the Java project and performing relevant
action. I create an aspect, TestAspect, in project A which defines a
pointcut on a Java source in B. It compiles, but there are no markers.
If I move the source from B into aspect project A, the markers appear.

Can I have a separate project with my aspects which weave into other
projects?

Versions:
AJDT 1.2.1, Build 20051220151004, AspectJ version: 1.5.0
IBM RSA 6.0 (Eclipse 3.0)
JRE 1.4.2

Thanks, y

Yes, it's possible.
If you make project B an AspectJ project (you don't have to have any
aspects in it!), you can add project A to the "aspect path" of
project B (under the project's properties pages). The weaving will then
take place in project A. Alternatively, if you want to keep project B as a
Java project, you could do the weaving in project A, by setting the
"in path" to be the output folder of project B.

Hope that helps,

Matt.

How do I add project A to the "aspect path" of project B? I see that I
can add JARs, External JARs, Variables and Class Folders, but I don't see a
way to add projects.

Use the Class Folder option and add the output folder (usually the "bin"
directory) of the other project.

Maybe we should add an explicit control to add projects - it would make it
a bit clearer.

Matt.
