Build taking too long to complete in my local system. It showing the message "95% emitting CopyPlugin" when I run "npm start" and waits for 7 or 8 hours to complete, even same thing happens when I make code changes if code change is one line or a class name change it again takes a long time to complete.

{
    "start": "npm run dev",
    "dev": "webpack-dev-server --progress --watch --env.buildFlavor development --mode development",
}

it working fine with my previous system with almost the same configuration as the new machine.

webpack: ^4.41.2"

OS: windows 10

Is there any solution to this problem?

What is the best way to debug and find out what is causing this issue?

Did you exclude node_modules in webpack rule? – Kostya Tresko Sep 21 '20 at 07:44
In webpackconfig file I find this code "exclude: /node_modules|src[\\\/]third-party/," so I think it is exluded node_module in webpack rule @KostyaTresko – Anudeep GI Sep 21 '20 at 07:51

Can you create a minimal public project with the same problem? – Hossein Moradi Oct 08 '20 at 20:06

You can use https://www.npmjs.com/package/speed-measure-webpack-plugin to see what is taking too long. – Prakash Kandel Oct 11 '20 at 01:56

You should post webpack config file. This does not give much to work with. Also add --verbose option to your command so we can see more details. – twboc Oct 11 '20 at 20:53
