Describe the Bug

An app I'm working on relies on dynamically generated API client and while this is a blast, we don't really want the generated files to be checked into git for several reasons (CI with type checking based on fresh generated APIs, clearer and more concise PRs without clutter due to generated code etc.).

However, if I add an ignored folder to inputs, it won't trigger the cache miss. After some digging, I found out that turbo actually pipes the inputs directly to git ls-files which isn't listing any of the ignored files.

One of the steps for what constitutes a cache hit vs. miss for a given task states the following:

Hash the contents of all not-gitignored files in the package folder or the files matching the inputs globs, if present

This led me to believe that no gitignored files are taken into consideration when hashing unless those files are specified in inputs. I think this should be documented more clearly if this is not the expected behaviour.

Expected Behavior

Take gitignored files into consideration when hashing, or add some other option for this kind of files.

To Reproduce

Let's say we have this .gitignore file:

packages/api/src/generated

And this turbo.json file:

{
  "pipeline": {
    "build": {
      "cache": true,
      "dependsOn": ["^build"],
      "outputs": ["dist/**"],
      "inputs": ["src/**/*.ts", "src/generated/**/*"]
    }
  }
}

When running turbo run build, hashing is not influenced by these generated files.
