This happens because you are using maven 2, but you need to use maven 3 
to build the engine. As there are no maven 3 packages in CentOS you will 
have to download and install manually maven 3:

1. Download the maven 3 distribution from the maven website, for example:

   wget 
http://mirror.lividpenguin.com/pub/apache/maven/maven-3/3.0.5/binaries/apache-maven-3.0.5-bin.tar.gz

2. Uncompress it to your favorite directory, for example to your home 
directory:

   tar xvf apache-maven-3.0.5-bin.tar.gz

That will create a apache-maven-3.0.5 directory.

3. Add the maven bin directory to your path. Assuming that you 
uncompressed it in your home directory:

   PATH=$HOME/apache-maven-3.0.5/bin:$PATH
   export PATH

It is important to put $HOME/apache-maven-3.0.5/bin before $PATH, as 
otherwise you will be using the maven 2 binaries.

You may want to put these two lines in your $HOME/.bash_profile file to 
make it persistent.

Once you do these three steps you can repeat the build and it should 
work fine.
