encountering errors on upgrading from v0.2.1

[ifuchs]

I would like to upgrade HA-Bridge from v0.2.1 and I do not see a prebuilt jar file (is there one?) so I am using mvn on OSX to build it. I am getting this error:

[INFO] BUILD FAILURE

As I am unable to use mvn to create the .jar. is there a pre-built jar I can download?
