ERROR in Error: The translation file (src/locale/messages.fr.xlf) locale must be provided

I am trying to create individual packages for each language.

I have used the below command for my angular 8 application which works fine. But when I use the same command in Angular. The translation file in that location. I am not sure why it is throwing that error.

ng build  --aot=true --prod --base-href=/Assignment/fr/ --i18n-file=src/locale/messages.fr.xlf --i18n-format=xlf --i18n-locale=fr --outputPath=../wwwroot/fr
