Angular 9 ngtypecheck

问题

After update to angular 9 i receives Warnings:

\src\main.ngtypecheck.ts is part of the TypeScript compilation but it's unused.
Add only entry points to the 'files' or 'include' properties in your tsconfig.
\src\polyfills.ngtypecheck.ts is part of the TypeScript compilation but it's unused.
Add only entry points to the 'files' or 'include' properties in your tsconfig.

my tsconfig.app.json:

{
  "extends": "../tsconfig.json",
  "compilerOptions": {
    "outDir": "../out-tsc/app",
    "types": []
  },
  "files": ["main.ts", "polyfills.ts"],
  "exclude": [
    "test.ts",
    "**/*.spec.ts"
  ]
}

How to solve these warnings?

回答1:

@Felix If you're using @angular-builders/custom-webpack package, warnings are caused due to @ngtools/webpack v9 dependency
