Re: [aspectj-users] Problems with RCP Application using AspectJ and Spr

[Andrew Eisenberg <andrew@xxxxxxxxxxxx>]

Are you using the ajdt headless build support?  The standard eclipse
pde headless build support will not compile aspects.

AJDT headless build support is available, but it is not officially
supported.  The bundle and instructions on how to use it are available
here:
