Re: [aspectj-users] AspectJ + Cobetura

Apparently, the theory is that you may have aspects in src/test/aspects that affect code in src/main/java, so it recompiles src/main/java and src/test/java to target/test-classes.  The cobetura-enhanced files in target/classes simply aren't seen while the tests are running.

Many people thing this is a questionable practice, and the plugin will soon have an option to turn off this behavior (off will likely become the default in the future), which should make it compatible with Cobetura.

Howard,

  Can you try from the ant or make maven plugin to use Cobertura 1.8?

  If I am not mistaken, Cobertura 1.7 has explicitly defined AJ
attributes, so I can't be sure if the list of those attributes in AJ
hasn't been changed since it was created in Cobertura.
  Cobertura 1.8 is using new ASM's "passtrough" mode for all unknown
attributes, so it should work for all AJ attributes as long as they not
using anything from class constant pool.

  BTW, what kind of error you are getting from m2 plugin?

  regards,
  Eugene
