Module Boundary Rules Not Enforced Due to Nx TargetProject Resolver Not Resolving Target Project Correctly

[qing-lin-007]

Current Behavior

In a monorepo that uses npm workspaces and relies on package name imports instead of path aliases, and each project’s package.json does not define a main or exports field. We are seeing issues when using @nx/eslint-plugin and @nx/eslint

The @nx/enforce-module-boundaries rule is not enforced because Nx’s target project locator fails to resolve the target project correctly.

In the example PR, running:

nx run cart:lint --skip-nx-cache

from the repo root does not produce the expected linting errors:

Expected Behavior

Running the above nx command should throw linting errors, just as native eslint does:

npx eslint 'apps/cart/**/*.{ts,tsx,js,jsx}' --cache=false

GitHub Repo

nrwl/nx-examples#404

Steps to Reproduce

1. Checkout the branch
2. yarn install
3. in the root, run: nx run cart:lint --skip-nx-cache
4. in the root, run: npx eslint 'apps/cart/**/*.{ts,tsx,js,jsx}' --cache=false
