Make sure to have the JDK version in your Build path and the version specified in the source tag match the same.

    org.apache.maven.plugins
    maven-compiler-plugin
    2.1
    
     **1.7**
       1.7
       true
    
 `

I had the build path pointing to jdk 1.7 and "1.6" in the source tag, when I corrected the version to 1.7 in source tag the issue got resolved.

Execute mnv clean and mvn package.
