Description

After generating a native client with the maven plugin, our project no longer compiles with version 5.0.0
The culprit are the

import javax.ws.rs.core.GenericType;
import javax.ws.rs.ext.ContextResolver;

statements in the new JSON.java. The cause of this is AFAICT: #7263
which introduces the dependencies to the jersey classes in the templates.

AbstractOpenApiSchema also has an import:

import javax.ws.rs.core.GenericType;

The generated client is no longer native but depends on jakarta.ws.rs, the new Dependency is nowhere documented

openapi-generator version

5.0.0 java (library:native) - works in 4.X so this is a regression

OpenAPI declaration file content or url

Any file should do, here is a minimal example

{
  "swagger": "2.0",
  "info": {
    "version": "1.0.0",
    "title": "api"
  },
  "host": "example.org",
  "basePath": "/api",
  "schemes": [
    "http"
  ],
  "consumes": [
    "application/json"
  ],
  "produces": [
    "application/json"
  ],
  "paths": {
    "/ping": {
      "get": {
        "description": "ping",
        "operationId": "ping",
        "responses": {
          "200": {
            "description": "ping successful"
          }
        }
      }
    }
  }
}

Generation Details

java - library: native

Steps to reproduce

generate the api and try to compile it. (In our case a project which does not depend on jakarta.ws.rs)

Related issues/PRs

Suggest a fix

Remove the jakarta.ws.rsdependencies from the templates if no anyOf, allOf is used
JSON.java and AbstractOpenApiSchema.java are not needed in this case. The unuses import in all model classes to JSON.java can also be left out

Also happens when switching the library to resttemplate

[carlkuesters]

Any news on this? I also just used the "native" template and saw that there are these javax.ws.rs dependencies. :(

Sadly I can't go back to 4.3.1, as I also need the "openApiNullable: false" option, which was introduced in 5.x

Same problem happens with resteasy used as library and version 5.4.0

same issue with okhttp-gson

It seems this issue is no longer valid. I tested with OpenAPI Generator 7.0.1, and no javax* or jakarta* imports were generated.

In addition, this also doesn't seem to be an actual issue in OpenAPI Generator 5.0.0. There, indeed the mentioned javax* imports are generated. But the generated pom.xml (.../target/generated-sources/openapi/pom.xml) contains the corresponding dependency on javax.ws.rs-api. Running mvn clean verify inside the generated .../target/generated-sources/openapi/ directory succeeds without errors.

I assume people in this thread used a different pom.xml instead of the generated one. In cases where users use their own pom.xml, the easiest "fix" is to copy the dependencies from the generated pom.xml to your custom pom.xml.
