Re: [aspectj-users] Using AspectJ Aspect with CDI and dependency injecti

["Alexander Kriegisch" <alexander@xxxxxxxxxxxxxx>]

Hi Eric.

The error comes from Maven Compiler, not from AspectJ Maven, i.e. Javac tries to compile something you probably want to be compiled by Ajc. Without seeing your POM I cannot say more, but the configuration with regard to those two plugins is probably the root cause of your problem.
