When doing mvn clean install of AG library, this is what I get when doing so as the very first message written out from Maven to the console:

[INFO] Scanning for projects...
[WARNING]
[WARNING] Some problems were encountered while building the effective model for org.jboss.aerogear:aerogear-android:apklib:1.2.0
[WARNING] 'parent.relativePath' points at org.jboss.aerogear:simplepush-server-parent instead of org.jboss.aerogear:aerogear-parent, please verify your project structure @ line 28, column 13
[WARNING]
[WARNING] It is highly recommended to fix these problems because they threaten the stability of your build.
[WARNING]
[WARNING] For this reason, future Maven versions might no longer support building such malformed projects.
[WARNING]

The thing is that when I have this project in aerogear-android folder, there is also project in aerogear-android/../aerogear-simplepush-server (I just have a common folder where all these AG repos are stored locally from GH).
