I accidentally broken the master when refactoring the code generation. Before codegen.py was called directly from the master. Now I'm calling it as part of the build process for the wkdeploy app instead.

We should refactor this later. From the wkdeploy app's build, we only need to generate the Java base classes, and from the wkpf library's build we only need to build the C code for native wuclasses. Right now both build everything (but it doesn't take long).
