# Exclude the reference library project folder in LINT with angular 10

I am trying to exclude the reference library project files while running the command npm run lint, but it is not working for me.

In the main application, I have added these code in the angular.json

Angular.json

 "lint": {
"builder": "@angular-devkit/build-angular:tslint",
"options": {
"tsConfig": [
"projects/pts-ngx/core/tsconfig.lib.json",
"projects/pts-ngx/core/tsconfig.spec.json"
],
"exclude": [
"**/node_modules/**",
"**/projects/ors-testtaker-bff/**"
]
}
}


I have the below file structure and trying to exclude the files inside API and MODEL folder
