I have tried following the instructions at After Installing Java JDK 7 For Mac OS X - mvn -version still shows java version 1.6.0_31 but they do not fix my issue. :-(
When I run:
mvn clean install
I get the following issue:

I have Oracle's JDK7 installed:
echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk1.7.0_55.jdk/Contents/Home
I added to my pom.xml because maven was some how deciding to use source and target of 1.5 rather than 1.7:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>
When I run:
mvn clean install -X
I see it is telling me that JRE is being used and not the JDK. But I cannot for the life of me change maven to use JDK instead of JRE. :-(

The fix was to delete tools.jar from my home directory in ~/Library/Java/Extensions
For an unknown reason I had a JDK5 version of it lying around in there.
You can also check and remove it if you have it in the root folder in /Library/Java/Extensions
