This is the output from java -version:

java version "1.7.0_25" Java(TM) SE Runtime Environment (build 1.7.0_25-b15) Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode)

This is the output from mvn -version:

Java version: 1.6.0_51, vendor: Apple Inc. Java home: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home Default locale: en_US, platform encoding: MacRoman OS name: "mac os x", version: "10.8.4", arch: "x86_64", family: "mac"

Bug in Maven: http://jira.codehaus.org/browse/MNG-4226

Workaround:

echo JAVA_HOME=`/usr/libexec/java_home -v 1.7` | sudo tee -a /etc/mavenrc

On Linux (at least), Maven uses $JAVA_HOME to locate the JVM it uses to run. Check that you have exported that environment variable, and that it points at the right place.
