Maven and Android Facebook SDK apklib

Question

So I am in the process of Maven-ing the facebook-android-sdk to include in our CI process.

facebook/pom.xml:

<?xml version="1.0" encoding="UTF-8"?>

    </plugins>
</build>
</project>

So running mvn clean package install builds and installs to the local repository as expected.

So that I can use it in my Android App pom.xml like so:

<!--Facebook sdk-->
<dependency>
    <groupId>com.facebook.android</groupId>
    <artifactId>facebook-android-sdk</artifactId>
    <version>3.0.0-SNAPSHOT</version>
    <type>apklib</type>
</dependency>

Building and running in Intellij works great no problem it pulls the dependency and adds into the correct places.

Problem

When I run via the Maven Travis CI commands which are:

mvn install -DskipTests=true

Then:

mvn test

Testing will fail with missing classes (that being the facebook ones). It seems like when trying to install and test via maven it doesn't pull in the facebook-android-sdk correctly.

So, is there an issue in building the dependency or do i need to run another magical maven command before it tries to run the mvn test?

The facebook fork is avaliable here: https://github.com/Bizzby/facebook-android-sdk

You can use available Maven repository created to host the Maven port of the latest facebook android api :
