buildDependencies not working as expected.

Bug report

What is the current behavior?

See pull request here https://github.com/webpack/webpack.js.org/pull/4311

I’m requireing a file in webpack configuration, but change to requireed file doesn’t invalidate the cache as per https://github.com/webpack/changelog-v5/blob/master/guides/persistent-caching.md#build-dependencies.

Here’s the related configuration for cache:

  cache: {
    type: 'filesystem',
    buildDependencies: {
      config: [__filename],
    },
    cacheDirectory: path.resolve(__dirname, '.cache/webpack')
  },

If the current behavior is a bug, please provide the steps to reproduce.

1. clone code from https://github.com/webpack/webpack.js.org/pull/4311
2. run yarn then yarn fetch:supporters and yarn start
3. open http://localhost:3000/api/cli/#configuration-options
4. change - to * here https://github.com/webpack/webpack.js.org/pull/4311/files#diff-53da17d70729ef08abbe0bc80f4cf2a701f0447084bf69be87873f5a064512e4R13
5. ctrl-c twice to stop dev server and run yarn start again
6. refresh http://localhost:3000/api/cli/#configuration-options, you can find - still there while i was expecting *.

What is the expected behavior?

Right now I have to run rm -rf .cache/webpack to clean up the cache.

I’ve tested the code with the latest webpack and it works as expected now, I think the warning regarding Can't resolve 'webpack.dev.js' could be fixed in another webpack-cli release, hence I’m closing this issue.

Yep, fixed
