Details

When using Rspack's experimental persistent cache feature with TypeScript configuration files, the build logs a warning about being unable to resolve relative imports within the config directory:

LOG from rspack.persistentCache
<w> BuildDependencies: can't resolve ./util in /Users/airadian/rspack-repro/rspack.
<w> - NotFound("./util")

This occurs even though:

1. The TypeScript import (import { BogusPlugin } from './util';) works correctly in rspack/rspack.config.ts
2. The build completes successfully
3. The file rspack/util.ts exists and is valid

The warning appears when:

• Running the first build with no cache
• After clearing the cache directory (node_modules/.rspack) and re-running it

Reproduce Steps

git clone https://github.com/Armine-i/rspack-repro.git
cd rspack-repro
npm install
rm -rf node_modules/.rspack
npm run build

The warning will appear in the console output.

Important: It only logs when there's no cache or if it's invalidated. Run rm -rf node_modules/.rspack before building to reproduce.

Expected Behavior

The persistent cache's buildDependencies feature should correctly resolve TypeScript relative imports (e.g., ./util) within the tracked directory without logging warnings.

Actual Behavior

A NotFound("./util") warning is logged during the build, suggesting the cache system cannot resolve the TypeScript import even though the file exists and TypeScript compilation succeeds.
