[REQ] New Jakarta+Eclipse JAX-RS templates

Is your feature request related to a problem? Please describe.

This feature requests is intended to get another, completely different implementation of the current jax-rs one. The current implementation depends on io.swagger imports, as well as jackson as Json provider.

However, with microprofile, new vendor-agnostic APIs have arrived.

Describe the solution you’d like

The new implementation is implementation- and vendor-agnostic. It is “just” a new set of templates which can easily be derived from the existing ones.

• org.eclipse.microprofile.openapi.annotations instead of io.swagger.
• javax.json instead of com.fasterxml.jackson.

Benefits: Most applicaiton servers, like OpenLiberty, already ship those MicroProfile standards. When not using this generator, we could ship our applications without jackson and/or swagger dependencies.

The new dependencies are:

    <dependency>
      <groupId>jakarta.validation</groupId>
      <artifactId>jakarta.validation-api</artifactId>
      <version>2.0.2</version>
      <scope>provided</scope>
    </dependency>
    <!-- JSON-B API -->
    <dependency>
      <groupId>jakarta.json.bind</groupId>
      <artifactId>jakarta.json.bind-api</artifactId>
      <version>1.0.2</version>
      <scope>provided</scope>
    </dependency>
    <!-- JSON API -->
    <dependency>
      <groupId>jakarta.json</groupId>
      <artifactId>jakarta.json-api</artifactId>
      <version>1.1.6</version>
      <scope>provided</scope>
    </dependency>
    <!-- OpenAPI -->
    <dependency>
      <groupId>org.eclipse.microprofile.openapi</groupId>
      <artifactId>microprofile-openapi-api</artifactId>
      <version>1.1.2</version>
      <scope>provided</scope>
    </dependency>

Optional: Instead of javax, prefer the new jakarta namespace:

    <dependency>
      <groupId>jakarta.ws.rs</groupId>
      <artifactId>jakarta.ws.rs-api</artifactId>
      <version>2.1.6</version>
      <scope>provided</scope>
    </dependency>

Describe alternatives you’ve considered

Using the current “jax-rs” implementation which is in fact “non-jakarta jax-rs plus Jackson plus swagger”. Bloats the war file due to shipping jackson and swagger

Hi, is there any updates on Jakarta upgrade?
