Re: [aspectj-users] Is there a way to binary weave selected classes from ant?

OK.  So, the problem has to do with incremental compilation (or incremental re-weaving).  I'm fairly certain that when using ant, all classes are rebuilt all the time.

However, there is an interactive mode for using the iajc ant task ('i' stands for interactive).  Look at the docs for the ant task:
http://www.eclipse.org/aspectj/doc/released/devguide/antTasks-iajc.html#antTasks-iajc-options

This might help you.

Thanks Andrew.

Here is some more details about what I am trying to do and may be you can suggest a better alternative.

I have some aspects with very simple pointcut that pick exception handler execution.
This aspect will only be used in development, and will not be deployed in production.

We have a large team of developers working on a code base having around 3500 class files.
Weaving all these classes, when a single file changes on the developer machines will add too much delay to the build cycle.
So I was looking for a way to weave only those class files that were re-compiled by ant-javac.
This will greatly increase the build speed for average case where developer only changes few files, compiles, test and repeats the cycle.

Yes, this is because the inpath argument will take all files located at a particular source root, run them through the weaver, and spit the results out at a different location.  It doesn't make sense to do this to only a subset of files at a location.

Rather than trying to fiddle with the inpath argument, a better approach would be to tailor your aspects so that they only touch the subset of files that you are interested in (eg- using the within(<type_pattern>) pointcut.

Hi,
I am integrating aspectj compile-time-weaving in an existing ant-based build.

I tried limiting <inpath> with ant's fileset combined with a <modified> selector. But its not working. It appears inpath only supports simple <path>s.

Is there a way to achieve this?
