Oracle released Java JDK 7 on April 26 for Mac OS X. I followed the install instructions and when I do java -version in a terminal window I get: java version '1.7.004' Java(TM) SE Runtime Environment (build 1.7.004-b21) Java HotSpot(TM) 64-Bit Server VM (build 23.0-b21, mixed mode) However when I do mvn -version in the terminal window I get. The Apple Java for OS X 2012-006 1.0 update for Mac OS X 10.7, 10.8 operating systems delivers improved security, reliability, and compatibility by uninstalling the Apple-provided Java applet plug.

To get JDK 7 up,
- I downloaded the JDK from Oracle. They have a nice dmg file, which makes it easy to install.
- After reading their installation instructions and running /usr/libexec/java_home (which I didn't even know about), it still wasn't defaulting to JDK 7.
Surgery required. So, I headed over to:
This is where the system jvm's are stored. You'll notice a symbolic link for CurrentJDK. It probably points to:
You're going to want to point that to the new JDK, which java_home tells us is located in:
So, the magic commands you need are:
Then, you should be good:

Since current Adobe installers and applications were built before these changes by Apple, Adobe software anticipates that Java is installed. Adobe and Apple have worked together to ensure that you can install Java at OS install time. Or it can be installed later before you install Adobe applications. At runtime, when you launch an Adobe application, you are prompted to install Java if it is not already installed. If you do not install Java before running an Adobe application, there can be missing or improperly behaving features. If you encounter any issues, install Java to correct the problems. Adobe recommends that corporate IT organizations pre install Java (or make sure that Java can be installed through their firewalls/security) to avoid conflicts with Adobe applications.
