anchor.diff:  The _codegen_ annotation processor generates these classes at compilation time. It is a feature of the Java
   compiler so _no extra step_ is required, it is just a matter of configuring correctly your build:
   
  -Just add the `io.vertx:vertx-codegen:processor` and `io.vertx:vertx-sql-client-template`
  +Just add the `io.vertx:vertx-codegen:processor` and `io.vertx:${maven.artifactId}`
   dependencies to your build.
   
   Here a configuration example for Maven:
  
positive.code: [source]
  ----
  annotationProcessor "io.vertx:vertx-codegen:${maven.version}:processor"
  compile "io.vertx:vertx-sql-client-template:${maven.version}"
  ----
  
  IDEs usually provide usually support for annotation processors.
