Thanks for your issue! This is not related to this repo. The reason: The builder API has changed with Angular 8. A PR for @ionic/angular-toolkit is already available but not published so far (see https://github.com/ionic-team/angular-toolkit/pull/132 )

At the moment Angular 8 is not supported.

If you cannot wait (like me 😉), just replace @ionic/angular-toolkit inside angular.json with paulstelzer-ionic-angular-toolkit and run npm i paulstelzer-ionic-angular-toolkit. This is the build of the mentioned branch. After @ionic/angular-toolkit got the new release you can use this again

Seeing this too after upgrading to Angular 8 and trying to run an ionic cordova build.
