ngc --watch ignores changes in templates (ivy) #31982
Description
🐞 bug report
Affected Package
The issue is caused by package @angular/compiler-cli
Is this a regression?
Yes, the previous version in which this bug was not present was: 8.1.2
(But, due to #31322, it only worked on every second change of a template.)
Description
- I run ngc in watch mode. Output directory is out-tsc.
- Ivy is enabled.
- I change a component's template.
- ngc says "File change detected. Starting incremental compilation."
- However, the template change does not result in an according change in the *.js file in out-tsc directory.
- For changes in *.ts files, it works.
🔬 Minimal Reproduction
Example project is at: https://github.com/stefanocke/angular-cli-app-with-rollup
Please run:
npm i
npm run ngc-app-watch
Then, change app.component.html and look for app.component.js in tsc-out.

Also closing as a duplicate.

@alxhub , thank you. Is it supposed to be part of Angular 8.2.2 ? It seems not to work yet.
Same result with 9.0.0-next.2.

@alxhub , it is still not working with 9.0.0-next.3
See https://github.com/stefanocke/angular-cli-app-with-rollup (steps tor reproduce see above)
