Well, I use JDK 1.7 on OS X Yosemite .  Both

java version "1.7.0_80"

Java(TM) SE Runtime Environment (build 1.7.0_80-b15)

Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode)

and
echo $JAVA_HOME    // /Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home
show JDK 1.7.
But for the Spark 1.4.1.  (and for Spark 1.2.2, downloaded 07/10/2015, I have  the same error when build with maven ()  (as sudo mvn -DskipTests -X clean package > abra.txt)

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/apache/maven/cli/MavenCli : Unsupported major.minor version 51.0

What does the following command say ?
mvn -version
