Repro steps

ng g library core --prefix=fc

The log given by the failure

Cannot read property ‘entries’ of undefined

Desired functionality

Would like go get my library 😄

Mention any other details that might be useful

I have tested on a fresh project and that works… My guess is that there is something wonky with the angular.json. We have been using the CLI for some time and belive that the upgrades along the way might have something to do with the issue.

Note: ng g c test works just fine
