Selective ignoring of components from being built

Sometimes, due to certain platform errors, some metadata components need to be ignored during build (especially for unlocked packages) while the same being required for other commands like validate . sfp offer you an easy mechanism which allows to switch .forceignore files depending on the operation.

Add this entry to your sfdx-project.json and as in the example below, mention the path to different files that need to be used for different stages

 {
  "packageDirectories": [
    {
      "path": "core",
      "package": "core-package",
      "versionName": "Core 1.0",
      "versionNumber": "1.0.0.NEXT",
      "default": true,
    }
  ],
  "plugins": {
        "sfp": {
            "ignoreFiles": {
                "build": "forceignores/.buildignore"
                "validate": ".forceignore"
            }
   }
 }
