Angular 14 "ng build" breaks concurrent "ng serve"

[hannobunjes]

Which @angular/* package(s) are the source of the bug?

common

Is this a regression?

No

Description

Consider a workspace with an application appand a library lib.

Run these commands

1. Run ng build lib --configuration development --watch, wait until it finishes
2. In another terminal, run ng serve app --configuration development, wait until it finishes
3. End the ng build lib process (note: this becomes necessary when ng build cannot build incrementally and a restart is required to run a successful build)
4. Repeat the command from step 1

Expected result is that ng serve continues working and uses the new version of lib.

Please provide a link to a minimal reproduction of the bug

Please provide the exception or error you saw

Compiled with problems:X

ERROR

projects/app/...../module.ts:33:8 - error TS2307: Cannot find module 'lib' or its corresponding type declarations.

33 } from 'lib';
          ~~~~~

and many other errors all relating to the fact that qer cannot be found even though the library was successfully compiled to the dist/qer folder.
Restarting ng serve fixes the issue.

Please provide the environment you discovered this bug in (run ng version)

Angular CLI: 14.2.10
Node: 14.21.1
Package Manager: npm 6.14.17
OS: win32 x64

This expected, as when you restart ng build all the libraries files are deleted which caused the application to rebuild with missing files.

To disable this behaviour, in your ng-package.json set "deleteDestPath": false.
