Is this a regression?

Possibly. It didn't exist in angular 11 (which is what I upgraded from), but cannot say if it was a thing in 12 or not.

Description

In angular 13 when I try and build prod (ng build project --configuration production) it fails because it cannot find the module webpack-sources. This is caused by license-webpack-plugin, and has been fixed in 4.0.0 (xz64/license-webpack-plugin#107), which fixed the issue for my project after I manually installed 4.0.0 as a devDependency of the project

🔬 Minimal Reproduction

Annoyingly it seems to not happen all the time, as I tried a fresh install (with all the same deps as my existing project) and the default angular project seemed to work.

Anything else relevant?

[epelc]

As of 4.0.0 license-webpack-plugin should work since it updates the dep for webpack-sources.

See xz64/license-webpack-plugin#107

Please bump license-webpack-plugin to 4.0.0

A temp fix is npm i --save-dev license-webpack-plugin@4 but not ideal.
