I don't think we should add repositories to the POM since this will pull this repo into the build of MapStruct users which might not be what they want. AFAIK POMs with repo information can't be deployed to Maven Central for that reason.

Instead I've provided a [maven-settings.xml](https://github.com/mapstruct/mapstruct/blob/master/maven-settings.xml) file with the JBoss repo which can be use via _mvn clean install -s maven-settings.xml_. I guess we should add this info to the readme file.
