create-nx-workspace@latest with Angular: Could not resolve dependency: jest

[TomONeill]

Current Behavior

After executing npx create-nx-workspace@latest and then executing npm i will fail with the following:

While resolving: @angular-devkit/build-angular@20.1.6
Found: jest@30.1.0
Could not resolve dependency:
peerOptional jest@"^29.5.0" from @angular-devkit/build-angular@20.1.6

This is indeed the case:
https://github.com/angular/angular-cli/blob/d67c2603f5437202d04927cbb277131c6f09945b/packages/angular_devkit/build_angular/package.json#L84

But the init project after creating the new workspace contains jest@30.1.0.

This is actually also the case when updating an existing project to the latest version.

To workaround the issue, add these overrides to package.json:

"overrides": {
    "@angular-devkit/build-angular": {
      "jest": "^30.0.2",
      "jest-environment-jsdom": "^30.0.2"
    }
  }

Another workaround is to lower the jest version from 30 to 29.5 as follows:

"@types/jest": "^29.5.0",

"jest": "^29.5.0",
"jest-environment-jsdom": "^29.5.0",
"jest-preset-angular": "~14.6.1",
"jest-util": "^29.5.0",
