JAVA1.6 upgrade 1.7 on MAC OS, and maven3.2.1 configuration

One, my Mac system

The preinstalled JDK is 1.6 and needs to be upgraded to 1.7 due to the need to use the Eclipse MARs 2 version

Second, download Java JDK http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html

Do not know why directly under very slow, later with the Thunderbolt super fast, the next good after the direct double-click on the line

Third, the new version will be installed in

/library/java/javavirtualmachines/jdk1.7.0_79.jdk/contents/home this path, the actual opening can see that eclipse is using this version of the JDK, but at this point Java_ Home didn't turn out to be the latest, so

In the/usr/kane user directory vim./BASHRC, make the following changes, MVN is already under the good, also set an environment variable here, and finally save the exit source./BASHRC can take effect
