The source code of the Java Platform, Standard Edition 11 Reference Implementations binaries is available under the GPLv2 in a single zip file. Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk/Contents/Home Anyway, open a new terminal and verify: echo $JAVA_HOME In previous macOS versions, this was done in ~/.bash_profile.
In ~/.zshrc, I set the variable like so: export JAVA_HOME=$(/usr/libexec/java_home)
#SETUP JAVA HOME FOR MAC UPDATE#
Here is a trick that allows me to keep the environment variable current, even after a Java Update was installed. JAVA_HOME is an important environment variable and it’s important to get it right. OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.9+11, mixed mode) OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.9+11) … hopefully showing something like this: openjdk 11.0.9 After opening a terminal, the successful installation of the JDK can be confirmed like so: java -version Select macOS and 圆4 and download the JDK (about 190 MB), which will put the OpenJDK11U-jdk_圆4_mac_hotspot_11.0.9_11.pkg file into your ~/Downloads folderĬlicking on the pkg file will install into this location: /Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdkĪlmost done. However, the easiest way is to select OpenJDK 11 (LTS), the HotSpot JVM, and macOS 圆4 is to get the latest release here:
#SETUP JAVA HOME FOR MAC HOW TO#
Easy to follow details about how to install OpenJDK are available here. As I’m writing this, Java 11.0.9 is the latest LTS (Long Term Support) version and AdoptOpenJDK is one of the best places to find Prebuilt OpenJDK Binaries. The next time you use IntelliJ you’ll see that JAVA_HOME is recognised correctly, and all is well with the world.Since OS X 10.7 Java is not (pre-)installed anymore, let’s fix that. The neatest way that I’ve found to support this is to add another line to your shell configuration like this: launchctl setenv JAVA_HOME `/usr/libexec/java_home` This is all well and good for terminal work, but graphical apps like IntelliJ IDEA will need some more work. Finally this variable is exported, meaning it will be available to sub-processes. They capture the output of the java_home command and then that value is assigned to the JAVA_HOME environmental variable. The back-ticks, `, in the command are important. Naturally if you don’t want to use the latest and greatest you could specify that you want to use the 64-bit JDK 1.7 like this: export JAVA_HOME=`/usr/libexec/java_home -d 64 -v "1.7*"` You can also put it in /etc/profile if you want it to be available to all users and not just yourself. This line would typically go in ~/.bashrc if you use bash or ~/.zshrc if you use zsh. export JAVA_HOME=`/usr/libexec/java_home` This helps us because we can simply do something like this in our shell configuration files to make JAVA_HOME always point to the latest JDK by default.
#SETUP JAVA HOME FOR MAC MANUAL#
The tool can do some other stuff too and the manual page is clear and concise. If that’s a bit wordy for you you can do the same thing by specifying the data model (bits) too: ➜ ~ /usr/libexec/java_home -d 32 ➜ ~ /usr/libexec/java_home -d 64 You can also do some cool stuff like filter by cpu architecture: ➜ ~ /usr/libexec/java_home -a i386 ➜ ~ /usr/libexec/java_home -a x86_64 I have omitted the JDK paths for brevity. You can also ask it to list all of your JDKs too by using the -V argument. ➜ ~ /usr/libexec/java_home /Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home The simplest usage of the tool will return the default JDK, which in my case is update 131 of JDK 1.8. OS X has had a very useful utility, since 2003, that allows you to easily generate a path to a JDK.
