[Jurigag]

Have the same issue, did you solve it?

[daveisfera]

I just disabled this plugin to continue testing with webpack 5

[eugeneoshepkov]

Isn't new webpack persistent caching making this plugin redundant?

[BuptStEve]

You're right~
webpack/webpack#6527

[yodfz]

this is pre webpack5

[alexander-akait]

You don't need this plugin with webpack@5, because webpack@5 support cache out of box https://webpack.js.org/configuration/other-options/#cache

[wearebear80]

@mzgoddard Could you please add this information to README.md file?

[CaoKejian]

In webpack5, HardSourceWebpackPlugin can be replaced by cache
