Install Java on Mac OS X
A short how-to for installing and configuring Java Development Kit on Mac OS X.
Java is core technology used by CI servers like Jenkins, Bamboo and others. It is also used by Atlassian CLI Client. In fact installing and configuring JDK is such a common task that it deserves its own post.
I find that for most applications I’m using 1.7, rarely 1.6 for some outdated and unsupported application. These days more and more applications are updated to work with 1.8 without issues.
Lots of applications, if not all, expect
JAVA_HOME environment variable to be set. This tells them where the Java Virtual Machine (JVM) is located. I would recommend to update your
~/.bash_profile and add something like this:
# Default Java Home. [[ -z "$JAVA_VERSION" ]] && JAVA_VERSION=1.7 [[ -s /usr/libexec/java_home ]] && export JAVA_HOME=$(/usr/libexec/java_home -v $JAVA_VERSION)
This is an over-devensive version. It can safely run on OS other than Mac, but will not set
JAVA_HOME in that case. It uses OS X specific
java_home executable found in
/usr/libexec. A very convenient utility to get JVM path for Java installation. Try
-V to get a list of all JVMs installed.
/usr/libexec/java_home -V # Sample output. Matching Java Virtual Machines (4): 1.8.0_25, x86_64: "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home 1.7.0_72, x86_64: "Java SE 7" /Library/Java/JavaVirtualMachines/jdk1.7.0_72.jdk/Contents/Home 1.6.0_65-b14-466.1, x86_64: "Java SE 6" /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home 1.6.0_65-b14-466.1, i386: "Java SE 6" /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home /Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home
If you are using shell other than bash, include the same in your shell’s version of
.bash_profile or source it directly with
