Desired functionality
if I use ng build lib-test , is working very well.
in the angular.json file, this version of @angular/cli, do not added automatically the neccesary :
"configurations": {
"production": {
"devServerTarget": "test1:serve:production"
}
}
and did not created the file: ng-packagr.prod.json
If I add those manually, the ng build --prod lib-test command, works just fine. So the issue is the fact that the above file and code is missing.
