[theotonge]

Expected Behavior

GitHub Repo

https://github.com/theotonge/nx-additionalEntrypoints-error-example

Steps to Reproduce

With repo

1. use windows
2. clone https://github.com/theotonge/nx-additionalEntrypoints-error-example
3. run nx build test-lib

Manually

1. use windows
2. create a react lib with bundler as rollup
3. modify project.json to:

  "name": "test-lib",
  "$schema": "../../node_modules/nx/schemas/project-schema.json",
  "sourceRoot": "libs/test-lib/src",
  "projectType": "library",
  "tags": [],
  "targets": {
    "build": {
      "options": {
        "main": "libs/test-lib/src/index.ts",
        "format": ["esm", "cjs"],
        "additionalEntryPoints": ["libs/test-lib/src/entrypoints/*.ts"],
        "generateExportsField": true
      }
    }
  }
}

4. create a file in libs/test-lib/src/entrypoints/thing.ts with an export
5. create a file in libs/test-lib/src/entrypoints/other.ts with an export
6. run nx build test-lib

Additional Information

The cause of the issue is because the createEntrypoints method is calling globSync from tinyglobby, passing a full windows path - tinyglobby only seems to support posix paths

As the paths are passed in as relative posix paths, working through the call stack I see that the paths are modified in withNx by calling path.join(workspaceRoot, entry) causing the conversion to windows path.

Replacing all separators at this point seems to solve the issue:

path.join(workspaceRoot, entry).replaceAll(path.sep, path.posix.sep)
