Description

Model classes generated with the combination of kotlin-server generator and jaxrs-spec library don't import jakarta packages when the config option useJakartaEe is set to true.

Actual result

import javax.validation.constraints.*
import javax.validation.Valid

data class CreateLocation (

    @JsonProperty("name")
    @field:Valid
    @field:NotNull
    @field:Size(min=1,max=512) val name: kotlin.String,

Expected result

I've submitted PR https://github.com/OpenAPITools/openapi-generator/pull/15618 to fix this issue.

This is very probably fixed with https://github.com/OpenAPITools/openapi-generator/pull/15593.

[drohne1673]

says merged. but it looks like it still doesnt work with version 7.0.1 of the plugin. i just tried in a quarkus app and the openapi-generator-maven-plugin 7.0.1: it still generates javax. Even after setting the configOptions is it ? "my solution" using microprofileRestClientVersion: "3.0" fixed my issue. the useJakartaEe option seems irrelevant.

[marcelstoer]

I can confirm that this definitely works with 7.1.0. Issue should be closed I guess.

This is only partly fixed. The config option useJakartaEe still produces this error, even though in our case we use the gradle plugin of the openapi generator (org.openapi.generator). It only works when setting as additionalProperties, which clashes with the documentation that says this would be only required for the CLI version.

This!

And I think the issue is that the code expects a Boolean vs a String, as

This works

    additionalProperties = mapOf(
        "useJakartaEe" to true
    )

But this doesn't

    additionalProperties = mapOf(
        "useJakartaEe" to "true"
    )

This had my scratching my head for a while.

I have a second error for it: the generated build file also has the wrong version of jakarta, at least updating it is what fixes intellij not recognizing the annotations.
