You should restart your current shell session to activate jenv export plugin echo export plugin activated.

Now let us set JAVA_HOME environment variable using command: $ jenv enable-plugin export They will be gone after we added Java in the next section. PATH : /home/ostechnix/.jenv/libexec:/home/ostechnix/.jenv/shims:/home/ostechnix/.jenv/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/binĪs, you can see, the output says the JAVA_HOME variable is not yet set and jenv is correctly loaded. Please check your path, or try using /path/to/java/home is not a valid path to java installation. Java binary in path is not in the jenv shims. Let us verify if jEnv is installed with command: $ jenv doctor $ echo 'eval '$(jenv init -)'' > ~/.zshrc If you are on Zsh shell, the commands to install jEnv are: $ echo 'export PATH='$HOME/.jenv/bin:$PATH'' > ~/.zshrc $ echo 'eval '$(jenv init -)'' > ~/.bashrc $ echo 'export PATH='$HOME/.jenv/bin:$PATH'' > ~/.bashrc If it doesn't work for any reason, just use ~/.bashrc instead of ~/.bash_profile. Next, initialize jEnv: $ echo 'eval '$(jenv init -)'' > ~/.bash_profileįinally, update the changes we just made in ~/.bash_profile using command.

Then, add jEnv to your $PATH: $ echo 'export PATH='$HOME/.jenv/bin:$PATH'' > ~/.bash_profile The above command will clone the contents of jEnv in a local directory named. Git clone jEnv repository using command: $ git clone ~/.jenv If you already have installed Java, just ignore this step. I am going to install openjdk 13 and 14 on my Ubuntu system: $ sudo apt install openjdk-13-jdk

You should install Java using your package manager or any other way of your choice. It will only manage the existing java installations. Please note that jEnv will not install Java for you. Set local or per-directory Java environment.Manage Multiple Java Versions With jEnv On Linux.
