error in compiling project having annotations in maven2

Question

I am using maven to compile some java classes. One of the classes has an annotation(@Override) so when i run mvn compile then I get error:

 annotations are not supported in -source 1.3
(use -source 5 or higher to enable annotations)
        @Override

 annotations are not supported in -source 1.3
(use -source 5 or higher to enable annotations)
        @Override

Although the java version in my system is jdk 1.6.29 still i can't understand this error. So i there a way by which i can check the jdk version maven is using and perhaps change it. Or, is there any other solution? Thanks.
