I have a project in version 5 of Angular, which generates a library using the rollup and works correctly. However I'm migrating from version 5 to version 6 of angular and wanted to use angular-cli, which already generates a library in the same pattern as the rollup. However when copying the code into src / app and running the ng generate library command, only a new project folder with a generic project is created, none of my files are automatically copied to the project folder. I would like to know how to do so that a new library is generated, using angular-cli in version 6, with the files that are within src / app.
