Do you have a reproduction? I don't think cache config will affect the content hash

cacheIdentifier will be insert to file in comments. so affect the content hash.

hash-sum will transform function to string to generate hash. so the linebreak will affect

// CONCATENATED MODULE: ./node_modules/cache-loader/dist/cjs.js?{"cacheDirectory":"node_modules/.cache/vue-loader","cacheIdentifier":"64bd234e-vue-loader-template"}

But comments are removed in production, and in development we don't add hashes.

This is the same to vuejs/vue-loader#1477.
webpack generate hash before remove comments

Got it. Thanks for pointing out.

One last thing before merging it: could you please run npx eslint --fix packages/@vue/cli-service/lib/PluginAPI.js in the project root? There're several style issues in the code.

😄Ok.Wait for tommorow morning~
I am not in office now.

I think webpack should generate hash by the last file to confirm hash last more time.

Users can get assets from cache.
