help understanding java compile issue for lombok.ast

[Hans-Christoph Steiner <hans@at.or.at>]

I'm packaging lombok and related things since the Android SDK Tools
depend on it.  They all build with a custom additions to ivy called
ivyplusplus, which I've packaged.  The build/compile process runs fine,
but it does not actually compile some of the .java files into .class
files.  Looking at the `ant -verbose` output of the build using my
ivyplusplus package versus the official ivyplusplus binary does not show
really any differences that I can spot.

The only differences I see between the two compilation logs are:

* the official ivyplusplus has:
    -target 1.8 -encoding UTF-8 -g -Xlint:unchecked -source 1.8
* my Debian ivyplusplus has:
    -target 1.7 -g:none -source 1.7

I'm currently building with openjdk-7, hence that difference, but it
still should generate .class files, or at least throw an error or warning.

Here's the build log using my ivyplusplus package:
