Install Java 7 and 8
People on the Stackoverflow cautioned not to install 8 until 7 is installed. So we are going to install JDK 7 first.
Unlike other version managers such as NVM, jEnv itself doesn’t install JDKs. You have to do it yourself. Luckily, Homebrew Cask made this task really easy. But before doing that, let’s check if we already have JDK 7 installed by Homebrew Cask:
install Java 7:
brew cask install java7
If you run into permission issue, add sudo at the beginning of the above command.
As of today, Java 8 is the latest stable. Run the following command to install Java 8:
brew cask install java
Install Java 8 Ubuntu
These two JDKs will be installed at the following directories. Your JDKs’ minor and patch versions might be different.
Enter jEnv
Now it is time to install jEnv:
brew install jenv
Add the following lines to ~/.bash_profile. This will initialize jEnv.
jEnv doesn’t install JDKs, so we have to tell jEnv where to look for them. Type these commands to register JDKs in jEnv (replace the minor and patch versions with yours):
After that, run this command to list all registered JDKs:
jenv versions
The version with an asterisk is the active version.
