$ jenv add /Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home If the above is correct, we'll go ahead and run the following command to add the location of this version to jenv If we cd into /Library/Java/JavaVirtualMachines we should see the following: Let's ensure that we know the location where the jdk package was installed, for MacOS Catalina, that should be under the following directory /Library/Java/JavaVirtualMachines Once the installation completes, we'll then follow up with jenv to add this version into our list of available version to be able to toggle between versions.

Before we go and download the version that we need, ensure that you run the following command to add the brew repo to your machine ( ). Now let's go ahead and download a brew cask for the jdk version that we are after. zshrc now that we have added a new command shortcut. Note: It's important that now you restart your bash terminal or run. $ echo 'eval "$(jenv init -)"' > ~/.zshrc $ echo 'export PATH="$HOME/.jenv/bin:$PATH"' > ~/.zshrc $ echo 'eval "$(jenv init -)"' > ~/.bash_profile $ echo 'export PATH="$HOME/.jenv/bin:$PATH"' > ~/.bash_profile
Next, ensure that jenv is listed as a command on your shell, if you are using bash, then run run brew upgrade)įirst, we need to install JEnv using homebrew, run the following command: The goal of this post is to show that we could do just that with Java, install a package to allow us to toggle between Java versions and set our JAVA_HOME path automatically for us just by running a few simple commands.īefore we start, ensure that you have homebrew installed and that you have updated all dependencies (ie. For those that come from NodeJS, installing a new version of Node is as easy as installing nvm and running nvm install and calling it a day.

With this little trick, you can write a Bash function/command to handle the terminal for your Mac development environment.I think its fair to say that going through the process of installing Java on any machine is in of itself a bit confusing. Java HotSpot(TM) 64-Bit Server VM (build 25.202-b08, mixed mode) Java(TM) SE Runtime Environment (build 1.8.0_202-b08) Verify Java 8 version just by: ➜ ~ java -version This can be done by following command: ➜ ~ export JAVA_HOME=`/usr/libexec/java_home -v 1.8` Therefore, the only thing we need to do is to config the JDK path for JAVA_HOME variable. Java_home works by validating the JAVA_HOME environment variable to determine the current Java version. In above result, Java 12 is the one being used. The bottom line indicates the current Java JDK being used, it means the version of Java when you type java -version. If you install more Java versions, it will show more on output. It will remove java formula completely from your Mac.Ĭurrent Java version can be verified by this: ➜ ~ /usr/libexec/java_home -Vġ2, x86_64: "OpenJDK 12" /Library/Java/JavaVirtualMachines/openjdk-12.jdk/Contents/Homeġ.8.0_202, x86_64: "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home
In case you want to uninstall a Java formula, use this command: $ brew cask remove java Well, install Java 8 should be done via this command: $ brew cask install java8Īfter that, you should have two Java versions, java12 and java8. Receiving objects: 100% (231/231), 95.43 KiB | 204.00 KiB/s, done.Īlright, let’s search for all Java formulas: $ brew search javaĪpp-engine-java google-java-format javarepl jslint4java libreadline-javaĬharles-applejava eclipse-javascript java java11 java8 netbeans-java-se yourkit-java-profilerĮclipse-java font-noto-sans-javanese java-beta java6 netbeans-java-ee oracle-jdk-javadoc homebrew/cask-versions/java-betaĪs you can see, there are java6, java8, and java11, which are LTS versions. Remote: Total 231 (delta 14), reused 56 (delta 5), pack-reused 0
Try this cask: $ brew tap caskroom/versionsĬloning into '/usr/local/Homebrew/Library/Taps/caskroom/homebrew-versions'.
Therefore, we will need a way to install Java 8. In reality, most of Java softwares are still under Java 8, not really upgraded to latest Java version. Homebrew always aims to bring latest version of software to install.
