anchor.diff:  
   The `ReactiveGreetingService` class contains a straightforward method producing a `Uni`.
   While, in this example, the resulting item is emitted immediately, you can imagine any async API producing a `Uni`. We cover this later in this guide.
  -
  -NOTE: In order to get Mutiny working properly with JAX-RS resources, make sure the Mutiny support for RESTEasy extension (`io.quarkus:quarkus-resteasy-mutiny`) is present, otherwise add the extension by executing the following command:
  -
  -[source,bash,subs=attributes+]
  -----
  -mvn io.quarkus:quarkus-maven-plugin:{quarkus-version}:add-extensions \
  -    -Dextensions="io.quarkus:quarkus-resteasy-reactive"
  -----
  -
  -Or add `quarkus-resteasy-reactive` into your dependencies manually.
  -
  -[source, xml]
  -----
  -    <dependency>
  -      <groupId>io.quarkus</groupId>
  -      <artifactId>quarkus-resteasy-reactive</artifactId>
  -    </dependency>
  -----
   
   Now, start the application using:
   
  
positive.code: Notice that the reactive PostgreSQL client already provides `Uni` and `Multi` instances.
  So you only transform the results from the database into _business-friendly_ objects.
  
  Then, let's use this `Fruit` class in the `FruitResource`.
  Edit the `FruitResource` class to match the following content:
  
  
negative.code:     -DprojectArtifactId=getting-started-reactive-crud \
      -DclassName="org.acme.reactive.crud.FruitResource" \
      -Dpath="/fruits" \
      -Dextensions="resteasy-reactive-jackson, reactive-pg-client"
  cd getting-started-reactive-crud
