Unsuccessful cordova build commands

I looked a bit at the Cordova Telemetry data about the commands executed:
https://datastudio.google.com/reporting/0B-Ja5cNOX_XLTElHdWd4V2NUem8/page/zkJF

I was mainly interested in the build process, so I filtered all non build related (`platform`, `plugin`, `create`, `help`, `info`, `version`, `requirements` and their typos) commands. This is what I was left with:


There are almost as many successful `run` executions as unsuccessful ones.
There are even _more_ unsuccessful `emulate` executions than successful ones.

Unfortunately we don't know more about interesting parameters like `--device`/`--emulator` or `--debug`/`--release` as those data is not part of telemetry collection.

The reasons for this high number of failures are of course manifold, but maybe we can still work on decreasing those numbers.
