Yes, I can reproduce the reported behavior. Presumably we forget to 
instruct the build process that it should not only skip building 
higher-level artifacts, but also installing.

Note, however, that the problem is purely of a cosmetical nature: Your 
file does get compiled as requested, and the error message you receive 
afterwards is for a step that you were not interested in anyway (and 
that could not possibly have succeeded, as the application binary is 
indeed not present).
