I need to migrate to NativeScript with WebPack 4

Question

I try to migrate to last NS version @nativescript/core@8.1.5 with nativescript-cli@8.1.4 and migrate my webpack.config.json to WebPack 5 is so difficult.

I try to migrate to nativescript-cli@8.0.2 (11-4-2021) with @nativescript/core@8.0.11 previous a new era with WP 5 but project fail with WP-cli:

[webpack-cli] Error: Unknown option '--env.hmr'

I try to create a HelloWorld project with:

• nativescript-cli@7.2.1 (11-3-2021)
• Node 14.16.0 (23-2-2021)
• NPM 6.14.11

And the project generate a package.json with:

"dependencies": {
    "@nativescript/core": "~8.1.1",

"devDependencies": {
    "@nativescript/webpack": "~5.0.0",

And when i run the project fails with:

[webpack-cli] Error: Unknown option '--env.hmr'
[webpack-cli] Run 'webpack --help' to see available commands and options
Executing webpack failed with exit code 2.

When I expected a project to be created with:

• @nativescript/core@7.3.0" (27-2-2021)
• @nativescript/webpack@4
