If the collection.json is not formatted in proper JSON schematics pukes and the error message is misleading. I understand the root cause was user error. However, the error message returned lead me down a deep path of questioning how the schematic was being resolved. Only when I started debugging the dev-kit/schematic code, was I able to determine the root of the issue.

Repro steps

When executing a schematic if the collection.json is not json formatted (in my case I was missing a brace) and error occurs.

The log given by the failure

Collection "@company/package" cannot be resolved.
Error: Collection "@company/package" cannot be resolved.

Desired functionality

Add a better error description would be useful, or do not swallow error.

Mention any other details that might be useful
