You need to change the <code>JAVA_HOME</code> environment variable to the new JDK 1.7 location.

Look at <a href="https://stackoverflow.com/questions/135688/setting-environment-variables-in-os-x">this question</a> for possible locations where JAVA_HOME might be defined. In a terminal, type <code>which java</code> to find the path of your Java installation, and then update <code>JAVA_HOME</code> to point to that path (but exclude the trailing bin folder).

You should use <code>JAVA_HOME=$(/usr/libexec/java_home)</code> instead on a Mac and then set the current jdk via "Java Preferences.app".

Set JAVA_HOME in ~/.profile

I think the problem lies partly with the java launch mechanism. I have been able to get Eclipse to run my code under Java7, but I think eclipse itself is still running under Java6. Also, I have a java program that was last compiled a year ago, and built using jarbundler-2.1.0.jar (with option jvmversion="1.6+"). When I double click the .app file it runs Java6, but when I double click the .jar file inside the .app it runs Java7.

Also, I do not use JAVA_HOME, but I still get the correct java version "1.7.0_04" shown in the question. JAVA_HOME seems to be a red herring. Maybe Maven needs it, but Eclipse doesn't seem to use it, and neither does launching jar files.

And after setting Java7 in the Java Preferences tool, it does not seem to affect launching .app java files. However it does make 'java -version' from the terminal work nicely. I tried unchecking everything but the Java7 option, and then Eclipse wouldn't run at all.

The reason Maven is still using Java 6 is that the /usr/bin/mvn script that launches it does not use the correct OS/X method for resolving the current Java version as specified in Java Preferences. See this Maven issue for details:

<a href="http://jira.codehaus.org/browse/MNG-4226" rel="nofollow">http://jira.codehaus.org/browse/MNG-4226</a>

Voting it up might get it fixed; in the meantime, if you alter the /usr/bin/mvn script as shown in the comments &amp; patch on that issue you will get the desired result.

Ok on my machine. Yes, the Oracle installer didn't exactly do its job, and it confused me to no end after 1.6 was still running.

but the SDK HOME is actually a sim link still pointing to 1.6

<code>/Library/Java/Home</code> in finder GetInfo points to <code>/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home</code>

in Terminal 

<pre><code>./Home -&gt; /System/Library/Frameworks/JavaVM.framework/Home

Go figure.

In case anyone is installing Maven on a 64-bit Mac running Mac OSX 'Mavericks' save yourself some time and some hair pulling trying to get Maven installed. I was trying to follow this (which failed because the location of the java_home has changed on Mavericks:

<a href="http://maven.apache.org/download.cgi" rel="noreferrer">http://maven.apache.org/download.cgi</a>

I was pulling my hair out until I found this website, which recommends you Install homebrew and follow the instructions on this page: <a href="http://techspunky.blogspot.in/2013/10/how-to-install-maven-on-mac-osx-109.html" rel="noreferrer">http://techspunky.blogspot.in/2013/10/how-to-install-maven-on-mac-osx-109.html</a>

once complete don't panic when $ maven -version doesn't work, instead use $mvn --version as maven.apache.org/download.cgi recommended. 

It worked, but then I noticed the Java SDK Maven was using was Java version: 1.6.0_65, which is not the latest SDK I installed on the system.

Once I set the JAVA_HOME=<code>/usr/libexec/java_home</code>

It was using the correct SDK: 
Maven home: /usr/local/Cellar/maven/3.1.1/libexec
Java version: 1.7.0_45, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "10.9", arch: "x86_64", family: "mac"

Success!
but wait...
next time I opened the terminal and ran mvn -v it went back to java version 1.6. WTH!

its some sort of supposed bug from what I read use:
echo JAVA_HOME=<code>/usr/libexec/java_home -v 1.7</code> | sudo tee -a /etc/mavenrc

and now:

Maven home: /usr/local/Cellar/maven/3.1.1/libexec
