Code does not work out of box

Describe the bug

Followup to quarkusio/code.quarkus.io#740 I downloaded the code, hit mvn quarkus:dev and after a while Quarkus started, but showed

[INFO] Invoking io.quarkus.platform:quarkus-maven-plugin:2.6.2.Final:generate-code-tests) @ quarkus-kie-test

Moving to the main repo. Can you please attach the project that you cannot build? Thanks.

I believe the root cause is that in https://github.com/quarkusio/code.quarkus.io/issues/740 I only selected the one thing that I am interested in and apparently (required) dependencies are not added into the pom.

When I e.g. add

    <dependency>
      <groupId>io.quarkus</groupId>
      <artifactId>quarkus-smallrye-reactive-streams-operators</artifactId>
    </dependency>

to the pom, the above error goes away, but new ones show up.

Is this still an issue?
