Repro steps

• ng update --next @angular/cli @angular/core @angular/angular-material

The log given by the failure

Cannot read property 'parseJson' of undefined

The update of CLI and Core succeeds despite the red error, but build-angular is not updated to the correct version and Angular Material and the CDK are not update.

Desired functionality

ng update succeeds

This didn't work for me in one of my projects: https://github.com/alfaproject/rs-progress/tree/v6

P.S.: It also didn't remove the reflect polyfill.

I saw this today as well with an ng update @angular/cli to 7.0.1. It did not update "@angular-devkit/build-angular": "^0.9.0", to "@angular-devkit/build-angular": "^0.10.1",.

This was also mentioned in https://github.com/angular/angular-cli/issues/12646#issuecomment-431317797.

@Splaktar this was due to a very specific underlying issue that manifested in the following output: Cannot read property 'parseJson' of undefined.

What you are experiencing is most likely this: https://github.com/angular/angular-cli/issues/12647

[Splaktar]

@clydin thank you for the clarification. I've moved some of the comments over to that issue.

It might be helpful to update the topic of this issue to ng update: Cannot read property 'parseJson' of undefined to avoid more people posting that they are seeing issues with build-angular.
