[Hawkular-dev] Logging ...

[John Mazzitelli]

Note that the annotation stuff has changed. All the annotations in org.jboss.logging has been deprecated. You need another dep called org.jboss.logging:jboss-logging-annotations - version 1.2.0.Final.

I believe it is not a runtime dependency - so I just put it in my parent pom with provided scope. All the annotations have a retention policy of CLASS, not RUNTIME, so I assume that means you don't need the annotations jar (and, in fact, the Wildfly 8.2 distro does not have it - the only thing in the org.jboss.logging module is the logging jar itself)

In addition, @MessageLogger requires you to specify "projectCode" attribute now. I'm sure there are other changes on the new annotations stuff. The example I found on the RH wiki is for the old annotations, I guess.
