The previous version in which this bug was not present was: 7

Description

When I build Angular 8 app with PWA in production mode, while "ngswConfigPath" in angular.json is not set correctly, build result depends on build command:

• ng build --prod does not show any error, build looks like successful
• npm run ng build -- --prod ends with ELIFECYCLE error without any detailed informations

🔬 Minimal Reproduction

1. ng new BugReportApp
2. ng add @angular/pwa
3. go into angular.json file and broke ngswConfigPath setting - IE set its value to "xxx"
4. at this point, running ng build --prod does not show any build error!?
5. running npm run ng build -- --prod shows only default error message without any useful informations

In Angular 7 same steps shown more useful error info in both cases.

🔥 Exception or Error

Only error shown while running build using npm is this one:
