Re: [aspectj-users] Aspects in dependent projects in Eclipse
|
I'm not sure why putting bin on inpath didn't work for you.
For out-of-memory, you might need to
- add memory to Eclipse when launching:
-vmargs -Xmx400m
and/or
- disable generation of structure view in AspectJ preferences
To debug when advice doesn't run as expected, see aspectj-users mail
"writing/debugging pointcuts" at
http://dev.eclipse.org/mhonarc/lists/aspectj-users/msg01609.html
To start, make the pointcut staticly-determinable
(no args/this/targer, if, or cflow...) and then write a declare
error with the pointcut; continue editing/fixing the pointcut
until it shows errors where you would expect. Then add any dynamic
(non-static) components of the pointcut back in and test with advice.
