ng add - please specify a project name

Bắt đầu bằng cách tái hiện luồng ng add @angular/material myapp trong một workspace chứa cả mylibrary và myapp, sau đó lần theo entry point của lệnh ng add. Hoàn thành khi lệnh chấp nhận tên project và cấu hình myapp cho Angular Material thay vì chỉ cài đặt package.

Repro steps

• Step 1
  starting a new project with ng new angular-project
• Step 2
  generate a library/application inside the new angular-cli project

  ng g library mylibrary
  ng g application myapp
  

• Step 3
  Add @angular/material

  ng add @angular/material myapp
  Installing packages for tooling via npm.
  Multiple projects are defined; please specify a project name
  

Observed behavior

@angular/material gets correclty installed in the node dependencies but the myapp project is not configured for using the library.

Desired behavior

The current ng add usage is: usage: ng add <collection>
Ideally this should allow passing the target app like this:

usage: ng add <collection> [options]
options:
  --project
      The name of the project.
