APT isn't very good at error recovery, and so in general when you see
some compilation errors like that, the schema generator that runs later
could die a horrible death, like this NPE.
But at least the first error message from apt is accurate. APT cannot
find your ComputerConfigListToMapAdapter. You need to make that
available to the compiler. I believe you can do so by either compiling
this class and passing that to schemagen via -cp, or specify the source
folder as -sourcepath. It's really the same as javac.
