AAR library examples using maven version 4.4.1

I was having trouble using android-maven-plugin to build an aar library for the first time, and realised the examples defaulted to version 4.4.1 .  When I change that version to 4.6.0, the examples no longer build for me.  The version should probably be updated: https://github.com/simpligility/android-maven-plugin/blob/master/src/test/projects/libraryprojects/pom.xml#L31
