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 (*) Current answers are either obsolete (no longer valid for macOS El Capitan or Sierra), or only address a single JDK, or do not address the system-wide aspect.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.

Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-462, mixed mode)Īdd the export JAVA_HOME… line to your shell’s 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
