what happen?

Answer 1

It says build was successful. The first warning is saying you use Java 7(1.7) where the source supports Java 6 (1.6). The second waring is a consequence of the first one. If your application works, i dont think there is any problem. If it doesnt work, try using java 1.6 or get the updated versions that support java 1.7.
