Re: [aspectj-users] Writing only weaved classes to destdir - not everyth

[Matthew Webster <matthew_webster@xxxxxxxxxx>]

Fabian,

The recommended approach to binary weaving
is to maintain the original modularity of the application i.e. weave each
JAR file separately and (optionally) give each one a modified name. This
will avoid difficulties deploying and configuring the application.The definition
of a cross-cutting concern and the packaging of the affected application
should be orthogonal.

Hi,

thanks for your prompt help.

As I see there is no direct way to get only the affected classes. So I
have to
think about a workaround here.

A .class scanner might be one solution. Or you take the weaveInfo string
and
extract the class information from it to copy only affected files. This
could be
done in a self written Ant task...

regards,
Fabian
