Re: [aspectj-dev] Query Regarding Maven Aspectj

[Andy Clement <andrew.clement@xxxxxxxxx>]

Hi,

It isn't clear to me when you are wanting the aspects to be woven in?

Are you doing compile time weaving (looks like you might be)?  In this
mode you can  just run the result with 'java', you don't need to see
javaagent.

Are you doing loadtime weaving? (where the aspects are separate to the
basecode and you want them applied as the application loads).  I don't
see the separate builds of basecode and aspects in the pom, but I do
see the javaagent being set for loadtime weaving.

If you are loadtime weaving you will need an aop.xml. Which you can
generate or write yourself, it simply lists the aspects:
<aspectj>
<aspects>
<aspect name="MyAspect"/>
</aspects>
</aspectj>
and will be looked up through your classpath (weaver expects to find
it in a META-INF subfolder).

Is your app code in app.jar?  If so, where are your aspects on the
classpath when you run it?  If they are also in app.jar and it was all
woven at compile time, just don't use the agent setting.

But I guess it comes down to my first question - do you want to weave
at compile time or later?  You have the choice.

cheers,
Andy
