generator-jhipster: JPA Derived Identifier combined with mapstruct generates code that doesn't compile

Overview of the issue

Combination of dto with mapstruct and use of jpaDerivedIdentifier doesn’t work.

Motivation for or Use Case

Generated code should compile

Reproduce the error

Use the following JDL:

application {
    config {
        baseName mapsIdBugWithDTO
        applicationType microservice
        databaseType sql
        prodDatabaseType postgresql 
    }
    entities *
}

entity A

entity B

relationship OneToOne {
  A to B with jpaDerivedIdentifier
}

dto * with mapstruct

<del>Because of #10739, once the application and entities have been generated with jhipster import-jdl, you have to manually fix .jhipster/A.json and .jhipster/A.json and regenerate both entities with jhipster entity A --regenerate --force and jhipster entity A --regenerate --force</del>

Then you have multiple compilation errors:
