browser-esbuild builder doesn't clean output path before building

[atsjo]

Command

build

Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

16.2.10

Description

output path isn't cleared before building with @angular-devkit/build-angular:browser-esbuild, as it is with @angular-devkit/build-angular:application and @angular-devkit/build-angular:browser.

and setting deleteOutputPath=true doesn't work either...

this makes old build artifacts accumulate in the output, since chunks get a new hash for every change...

I could migrate to using application builder, but that puts the browser build in it's own sub-dir, with 3rdpartylicenses.txt in the parent folder (which is linked in my web-app)...

Minimal Reproduction

1. setup project with browser-esbuild
2. build
3. make a change in the app
4. build
5. observe output with old hashed chunks

Anything else relevant?

I'm using nx, and the reported Package Manager above is wrong...
Using the application builder works, but then I must manipulate the build output before deploying. The docs also states that deleteOutputPath can be set, but it's not working...

btw; the reason typescript is not updated is a problem with the language service
angular/vscode-ng-language-service#1959

Facing the same problem. The output is not deleted if "deleteOutputPath": true is explicitly specified.
