Entity generator do not ask for fieldType when no persistence

[henri-tremblay]

Overview of the issue

I have generate a project which use "No database". I'm generating an entity for it.
It used to be forbidden but in version 7.0.0-beta.0 it seems to now be allowed, which is really cool.

The following things do not work:

1. The generator doesn't ask for any field type. The field type is undefined and the generator fails with an error
2. Repository classes are generated
3. Service and IT tests are referring to the repository (which causes compilation errors and a crash in prettier)
4. The entity is annotated with @Id

Motivation for or Use Case

I want a read-only script that will present information coming from calls on other APIs.
So I don't need the persistence but having the UI and controllers is really useful.

Reproduce the error

1. Generate a project with no persistence
2. Create an entity

Suggest a Fix

• Field type should be asked. The list is probably coming from the persistence type so I suggest some hardcoded list (String, LocalDate, Integer, ...)
• The generated code should have no JPA annotation on the entity
• The repository classe should not be generated
• The service should be generated without using a repository and with not content (todos, empty Optionals and empty lists)
• The IT tests should use no repository. It could check that empty stuff is indeed returned

Side comment: "languages": ["en", "fr"] is weird. I have generated without international support and English as the language.

Issue it still valid with beta-1
1- Create a project without a database
2- Add an entity (jhipster entity Item) with whatever field (e.g name)

• No type asked
• Error right after because of it

ERROR! fieldType is missing in .jhipster/Item.json for field {
    "fieldName": "name"
}

This issue is stale because it has been open for too long without any activity.
Due to the moving nature of jhipster generated application, bugs can become invalid.
