Yesterday during one of the changes I made about dependencies I removed the committed eclipse project file which setup the annotation processors for Eclipse, mainly because it was not valid anymore with the current dependencies. Fred Bricon from the JBoss Tools team is working on https://issues.jboss.org/browse/JBIDE-8208, I've tested his work yesterday on both Infinispan and Hibernate projects: it's awesome, and the project will not need anything more than a standard maven project import to be setup properly. The integration is very nice, for example if you now make a mistake in the logger annotations (like a duplicate logging ID) Eclipse will immediately highlight it as compile error - again without needing to configure anything in the IDE; as soon as [LOGTOOL-20] will be included in the next version of the annotation processor we'll even get errors of mismatching parameters with the message placeholders as "%s". There's one side note: this update of the plugin was not released yet, so please be patient and for the time being configure the annotation processors manually and avoid committing that in the project as it will conflict with the plugin work. The main difficulty in configuring the APs is gone (duplicate conflicting classes on classpath), so you only have to tick the annotation processors checkbox to "enabled", if it's not already.
