Fix maven branch compile error.

[carlwilson]

Maven output below, it's probably an easy fix but am concentrating on getting the pieces in place at the moment.

@carlwilson The problem lies within these two lines in the pom.xml

<sourceDirectory>src</sourceDirectory>
<testSourceDirectory>tests</testSourceDirectory>

It is not a good idea to overwrite mavens src and test dirs. I am not sure why @calvinwo has done it. Maybe there is a specific reason for this. Once you remove these lines, the build works again as expected.

Nonetheless, the problem that I see with this branch is that the whole maven repository is still local. It is great that calvinwo has converted the needed libraries to maven branches. Maybe we can push the ones that are not in any public maven repository to a OPF maven repo (I guess there is one) and use the rest from the official mavenrepo.

What do you think?
