NS 7 with Angular application entry point not being found

tsconfig.tns.json 周辺の移行動作と nativescript.config.ts のエントリーポイント設定から始め、次に webpack.config.tns.js を確認し、ns migrate に続けて ns run android を実行して再現します。移行後の Angular code-sharing プロジェクトを、不正な HTML またはアプリケーションのエントリーポイントがないことによるエラーなしでコンパイルして実行できれば完了です。

Describe the bug

After upgrading a code sharing project with Angular to version 7 (using ns migrate) produces a project that results in the following errors being thrown when ns run android is run.

• Web project only HTML files are being flagged as invalid. (It seems these files are being included regardless).
• Application entry point file not found error, even with "main": "main.js" is defined in package.json or nativescript.config.ts

I noticed that during migration, the old tsconfig.tns.json is removed. Without this the project doesn't even start up and notes that a tsconfig file cannot be found. Adding back in my original tsconfig.tns.json file allows the compilation process to start but then throws up the aforementioned errors.

My tsconfig.tns.json

{
  "extends": "./tsconfig.base.json",
  "compilerOptions": {
    "module": "esNext",
    "target": "es2015",
    "moduleResolution": "node",
    "skipLibCheck": true,
    "resolveJsonModule": true,
    "paths": {
      // Paths removed for clarity
    }
  },
  "files": ["apps/my-app/src/main.tns.ts"]
}

My nativescript.config.ts

// Identifiable names changed / removed
import { NativeScriptConfig } from '@nativescript/core';

export default {
  id: 'com.company.my-app',
  appResourcesPath: 'apps/my-app/App_Resources',
  android: {
    v8Flags: '--expose_gc --harmony_destructuring',
    markingMode: 'none',
  },
  appPath: 'apps/my-app/src',
  main: 'main.js',
  nsext: '.tns',
  webext: '',
  shared: true,
  useLegacyWorkflow: false,
  webpackConfigPath: './webpack.config.tns.js',
} as NativeScriptConfig;

It is worth noting that this project is included within a @nrwl/nx workspace and was working perfectly prior to the upgrade process.
