Ignore folder in project construction for production

Question

Hello,

I’d like when to execute the ng build --prod angular ignores a folder and its contents inside the folder assets.

I tried using the following configuration inside the.json angular, it even works, but it is also applied when running ng serve resulting in file not found error.

"assets": [
          "src/favicon.ico",
          {
            "glob": "**/*",
            "input": "src/assets",
            "ignore": [
              "**/configuracao/*"
            ],
            "output": "/assets"
          }
        ],

But I want this to apply to production only.

Anybody got any ideas? Thanks in advance!
