JAVA_HOME decides which java is used by some things, but the java you get when you just type java is /usr/bin/java, and that executable is actually just a wrapper that picks a java to run from amongst all installed versions. The -v option is mostly for scripting, and that's how we're using it here). The -V option lists all and is meant for your eyeballs, not for scripts. here, assign it to the JAVA_HOME env var. (the backticks mean: Run this then take the output of it and treat that as the 'value' of the expression. To 'override', you can use something like (depends on which shell you're using on your mac): export JAVA_HOME=`/usr/libexec/java_home -v 17` To see all installed javas, you can run: /usr/libexec/java_home -V Also, yes, if you just run java without specifying which one you want, you so happen to get java13 here. the java8 to java9 transition broke a ton of stuff, much of it needless and much of it not reasonably expectable or fixable by libraries and apps, so a bunch of java apps and libraries only run on java8 - just an example). This is often required java is not backwards compatible (it tries to change little, but e.g.

So basically just stick /Contents/Home/ in between the paths above.Java doesn't mind if you install multiple versions. Instead of jdk-8xyz/bin, the folder structure is jdk-8xyz/Contents/Home/bin. copy the icedtea/icedtea-web-docs/ folder to the jdk-8xyz/icedtea-web-docs/ folder.įor the Mac, the folder for the main JDK is different: copy the icedtea/share/doc/icedtea-web/ to the jdk-8xyz/share/doc/icedtea-web/ folder copy the icedtea/share/pixmaps/ to the jdk-8xyz/share/pixmaps folder if ico doesn't already exist there. copy all 4 icedtea/share jar files to the jdk-8xyz/share/icedtea-web folder copy the iced-tea/bin/policyeditor.exe file to the jdk-8xyz/bin folder copy the iced-tea/bin/itw-modularjdk.args file to the jdk-8xyz/bin folder (if not exists) copy the iced-tea/bin/itweb-settings.exe file to the jdk-8xyz/bin folder (if not exists)
copy the iced-tea/bin/javaws.exe file to the jdk-8xyz/bin folder

If installing a Mac, or Windows 32 bit installation, the iced-tea project is not an optional install of the main JDK MSI or Pkg. Return to the Terminal window still open, enter the java_home command again, this time, we should see that the JVM is installed.
jdk-13.0.2.jdk from the Downloads Finder window into the JavaVirtualMachines Finder window. If the JavaVirtualMachines folder does not exist create it.ĥ. We had to create the folder inside the Library folder. On one of our machines that never had a JVM (Java) installed, we didn't have a Java folder.
In the pop-up, enter /Library/Java/JavaVirtualMachines/ and click Go. Leaving the Downloads Finder window open, open another Finder window via the Finder menu Go -> Go to folder. The result will be a folder with the same version:Ĥ. Once downloaded, open the Downloads folder, locate the tar.gz file, and double-click to expand/decompress the archive. JDK 13.0.2), under the Build "x" header, click the tar.gz macOS/圆4 link.ģ. On the JDK General-Availability Release page for this version of Java (e.g. Using your web browser, visit the OpenJDK Downloads page at Java.Net:īeside the Ready for use label, choose the current version:Ģ. Leave the Terminal window open or minimized.ġ. Our Java JVM will be added inside this folder. If no result, run # mkdir JavaVirtualMachines to create the folder. If no result, run # mkdir Java to create the folder. Using the same terminal window, perform the following, as needed: If this Mac has never had a Java JVM installed, all the folder structure needs to be added. They are installed separately (Hint: IcedTea project at ). At this writing, the OpenJDK version does not include the javaws and JLNP. Specifically, we will be adding the Java program for "all users" by adding the Java/JVM to the main /Library/ folder structure instead of the current user ~/Library/ folder structure. We just have to use the correct directory structure, as the directory path above. With MacOS, we can have more than one Java (JVM) installed. To check, open a new Terminal window, and check:Īfter we are done this task, this command will output our new virtual machines.ġ3.0.2, x86_64: "OpenJDK 13.0.2" /Library/Java/JavaVirtualMachines/jdk-13.0.2.jdk/Contents/Home The later versions of Apple MacOS uses the /usr/libexec/java_home program to locate Java versions and do that pop-up to install the Oracle one after you de-installed the Oracle version. Replace the Oracle-branded Java with OpenJDK version (still Oracle maintained).
