I think since the newly introduced logger, the compilation error/warning messages are displayed like this:

00:53:54.418 [Worker-253] ERROR o.a.h.AnnotationHelper:110
- @org.androidannotations.annotations.Bean cannot be used on a private element

I think all information except the message after the dash is totally unnecessary to print, it does not help the programmer to resolve the compilation problem. Moreover, this additional information draws the attention away from the real issue.
