      As HttpServletRequest and ServletContext can be injected without error, you can workaround this issue by obtaining HttpSession through HttpServletRequest like the following code:

          @Inject
    javax.servlet.http.HttpServletRequest request;

    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String hello() {
        HttpSession session = request.getSession();
        System.out.println("# session.getId()=" + session.getId());
        return "hello";
    }

      1. Extract the attached reproducer.zip
      2. Start Quarkus dev mode

      $ cd reproducer
$ ./mvnw clean compile quarkus:dev

      Then, you will see the UnsatisfiedResolutionException during the build phase

      CDI specification[1] defines HttpSession as one of the supported additional built-in beans. However, when an application has an injection of HttpSession like the following code[2] and runs with `./mvnw compile quarkus:dev`, Quarkus throws UnsatisfiedResolutionException with the following stacktrace[3] during the build phase.
      An injection of HttpServletRequest, HttpServletResponse, or ServletContext works fine, so it appears that only support for injection of HttpSession is currently missing.

      [1] https://jakarta.ee/specifications/cdi/2.0/cdi-spec-2.0.html#additional_builtin_beans

      A servlet container must provide the following built-in beans, all of which have qualifier @Default:

      • a bean with bean type javax.servlet.http.HttpServletRequest, allowing injection of a reference to the HttpServletRequest
      • a bean with bean type javax.servlet.http.HttpSession, allowing injection of a reference to the HttpSession,
      • a bean with bean type javax.servlet.ServletContext, allowing injection of a reference to the ServletContext,

      [2] example code

      @Path("/hello")
public class GreetingResource {

    @Inject
    public HttpSession session;

    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String hello() {
        System.out.println("# session.getId()=" + session.getId());
        return "hello";
    }
}
