Support exclude rules config for cache.buildDependencies

Feature request

What is the expected behavior?

Exclude some files/directories from the buildDependencies collected by FileSystemInfo.resolveBuildDependencies()

What is motivation or use case for adding/changing the behavior?

Sometimes some loader reads config from projectRoot/package.json by require() (for example postcss-load-config -> lilconfig) in this case projectRoot/package.json will be collected as a buildDependency by FileSystemInfo.resolveBuildDependencies(), and any change of projectRoot/package.json (such as project dependency update) will cause the invalidation of the full filesystem cache.

Actually I have not written any postcss config in my package.json file, so I want a exclude rules config to remove projectRoot/package.json from the buildDependencies.

How should this be implemented in your opinion? Support exclude rules config for cache.buildDependencies

Are you willing to work on this yourself? yes

Ok, actually I can pass a load config to lilconfig to read package.json by fs.readFile instead of require to avoid this problem. Thanks for your replies. @vankop @alexander-akait

But, it will take more than 30s to re resolve build dependencies…
