After installing Maven3 and cloning this repo, I ran "mvn package" in the root of the project.

Then I got an error as fllows. Does anyone have ideas to fix this?

1. You are using very old Java 7, please update to latest 1.7.0_25 (I had Eclipse crashes on 1.7.0_10)

2. I am using Maven 3.0.5, I will wait 3.1.1 to see if it had major issues, if not I will update to 3.1.x
