If the value of the "name" property in the flogo.json file differs from the directory created by flogo create (in src dir) then "flogo build" will panic.

I used "flogo create" to create an instance of an app. I then copied over the flogo.json file with a version containing the kafka trigger (rather than hand editing the file) and then attempted the build:
