Your Maven is reading Java version as 1.6.0_65, Where as the pom.xml says the version is 1.7.
Try installing the required verison.
If already installed check your $JAVA_HOME environment variable, it should contain the path of Java JDK 7. If you dont find it, fix your environment variable.
also remove the lines
