Schematics incompatibility with recent nx versions

[Szymon Schläpfer]

Hi there,

I've noticed an issue while using this schematics tool. The problem is that generation of a domain library fails, probably during an update of workspace.json file.

Library versions:

• @nestjs-architects/nx-ddd-plugin: 2.0.1
• nx & @nrwl/* dependencies version: 14.3.1.

Repro steps:

1. npx create-nx-workspace my-workspace --preset=nest (provide some app name, let's say my-app)
2. cd my-workspace
3. npm i -D @nestjs-architects/nx-ddd-plugin
4. nx g @nestjs-architects/nx-ddd-plugin:add
5. nx g @nestjs-architects/nx-ddd-plugin:domain my-domain

Expected behavior:

• libs/my-domain directory is created and contains 3 library directories
• workspace.json is updated
• import mapping added to tsconfig.base.json, paths object
• each generated library should have project.json file, allowing to add tags to enforce module boundaries by linter.

Actual behavior:

• libs/my-domain directory is created with subdirectories that contain library boilerplates,
• libraries don't have project.json file
• workspace.json file is not updated
• import mappings are not added to tsconfig.base.json,

Following stack trace appears:
