+					Use the Nexus Staging plugin as a full replacement for the standard
+					Maven Deploy plugin.
+					See https://github.com/sonatype/nexus-maven-plugins/tree/master/staging/maven-plugin
+					why this makes sense :-)
+					We can control whether we want to deploy to the Eclipse repo or Maven Central
+					by a combination of the version being a SNAPHOT or release version and property
+					skipStaging=true/false.
+					In any case we can take advantage of the plugin's "deferred deploy" feature which
+					makes sure that all artifacts of a multi-module project are deployed as a whole
+					at the end of the build process instead of deploying each module's artifacts
+					individually as part of building the module.
