$ java8įor more info you can see this post: How to Use Brew to Install Java on Mac 0 T19:05:50+00:00 T19:05:50+00:00 Answer LinkĬonsider the following approach only to change the JDK for each and specific tab of your terminal (i.e: iTerm).
zshrc for the aliases to take effect: $ source ~/.bash_profileħ - Finally you can use the aliases to switch between different Java versions. In this case, we want to be able to switch between Java8, Java11, Java13 and Java14: export JAVA_8_HOME=$(/usr/libexec/java_home -v1.8)Įxport JAVA_11_HOME=$(/usr/libexec/java_home -v11)Įxport JAVA_13_HOME=$(/usr/libexec/java_home -v13)Įxport JAVA_14_HOME=$(/usr/libexec/java_home -v14)Īlias java8='export JAVA_HOME=$JAVA_8_HOME'Īlias java11='export JAVA_HOME=$JAVA_11_HOME'Īlias java13='export JAVA_HOME=$JAVA_13_HOME'Īlias java14='export JAVA_HOME=$JAVA_14_HOME'Ħ - Reload. Switching between different versions of Java, you only need to add the following to your. $ brew tap adoptopenjdk/openjdkĥ - Switch between different versions of Java $ brew tap homebrew/cask-versionsģ - Install the latest version of Java $ brew cask install javaĤ - Install the other needed versions of Java (Java8, Java11, Java13). $ ruby -e "$(curl -fsSL )"Ģ - Install Homebrew Cask. I will share my experiences with macOS Big Sur v11.4, the best way to deal with these problems is by installing java using Homebrew:ġ - Install Homebrew. Just follow the steps but in step 4 just do $ brew install. With macOS Monterey, v12.0.1 Cask is no longer a Brew command. Same for jenv, it's cool and all, but as far as I can tell it merely changes environment variables, so it has the same limitation. It won't affect an application started from OS launcher (unless you change the right file and logout/login, which is tedious). Many explain how to change $JAVA_HOME, but this only affects the current shell and what is launched from there. (*) Current answers are either obsolete (no longer valid for macOS El Capitan or Sierra), or only address a single JDK, or do not address the system-wide aspect.
When working in a shell with alternate JDK, pick your method among existing answers (jenv, or custom aliases/scripts around /usr/libexec/java_home, etc). System launcher will use the JDK with highest version among those that have an ist file. It will simply be ignored by system's java command. That JDK can still be used when $JAVA_HOME points to it, or explicitly referenced in a script or configuration.
To exclude a JDK from being picked by default, rename its Contents/ist to.The system will pick the highest version by default. leave all JDKs at their default location, under /Library/Java/JavaVirtualMachines.The following approach works with Java 7 to 12 at least (early access at the time of this writing), with Oracle JDK or OpenJDK (including builds by AdoptOpenJDK produced after mid-October 2018). I want to control system's default, and that should be latest stable. when I start my IDE) to use the latest "early access" version I have for now. Usually I have the latest stable one for general use, and others for tests. As far as I can tell, none of the current answers do that (*).Īs a developer, I use several JDKs, and I want to switch from one to the other easily. This answer is an attempt to address: how to control java version system-wide (not just in currently running shell) when several versions of JDK are installed for development purposes on macOS El Capitan or newer (Sierra, High Sierra, Mojave). zshrc file should work: nano ~/.zshrcĮxport JAVA_HOME=$(/usr/libexec/java_home -v 1.8.0) Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-462, mixed mode)Īdd the export JAVA_HOME⦠line to your shellâÂÂs init file.įor Bash (as stated by antonyh): export JAVA_HOME=$(/usr/libexec/java_home -v 1.8)įor Fish (as stated by ormurin) set -x JAVA_HOME (/usr/libexec/java_home -d64 -v1.8) Now when you run java -version you will see: java version "1.6.0_65" Or you can specify just the major version, like: export JAVA_HOME=`/usr/libexec/java_home -v 1.8` Pick the version you want to be the default (1.6.0_65-b14-462 for arguments sake) then: export JAVA_HOME=`/usr/libexec/java_home -v 1.6.0_65-b14-462` Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdk/Contents/Home First run /usr/libexec/java_home -V which will output something like the following: Matching Java Virtual Machines (3):ġ.8.0_05, x86_64: "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdk/Contents/Homeġ.6.0_65-b14-462, x86_64: "Java SE 6" /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Homeġ.6.0_65-b14-462, i386: "Java SE 6" /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
