Type these commands to register JDKs in jEnv (replace the minor and patch versions with yours):
Brew cask install java permission denied install#
Now, you can see multiple versions of Java installed in your MacOS. jEnv doesn’t install JDKs, so we have to tell jEnv where to look for them. To install Java 8 run the following command:Īll the versions will be installed at /Library/Java/JavaVirtualMachines/Īwals-MacBook-Air:~ awal$ cd /Library/Java/JavaVirtualMachines/Īwals-MacBook-Air:JavaVirtualMachines awal$ lsġ.6.0.jdk jdk1.7.0_80.jdk jdk1.8.0_144.jdk If you run into permission issue, add sudo at the beginning of the above command. To install Java 7 run the following command: It will be installed at /Library/Java/JavaVirtualMachines/ To install Java 6 in OS X, download it from the Apple webiste. But, some of the application that I need to use regularly needs older Java versions. I have the latest Java 8 already installed in my system as shown in the screenshot below.Īs of today, Java 8 is the latest stable. The asterisk is the version currently selected. * system (set by /Users/ajones/.jenv/version)įor me, it only found the system Java but no other version is detected. Now it’s installed, lets see what versions of Java it can find: If which jenv > /dev/null then eval “ $(jenv init -)“ fi $ brew update & brew upgrade brew-cask & brew cleanup & brew cask cleanupĬreate ~/.bash_profile and add the following lines there. If your Homebrew Cask needs to be updated and upgraded: Install Homebrew Cask if you don’t have it:
Brew cask install java permission denied how to#
After that, I’ll show how to manage different java versions using jEnv. It’s wired that most of those applications performs best with different individual Java versions and mostly with older versions like CTC works better on Java 6, ASDM works better on Java 7 and the latest Java version is now 8.Īfter taking my new MacBook Air, it became a serious concerns to me running and managing multiple versions of Java on my MacOS until I found jEnv. jEnv allows you to switch to different versions of Java using simple commands.įirst, I am going to use Homebew package manager and Homebrew Cask app manager to install Java 6, 7 and 8. After getting my new job roles of managing the transmission and data network in BdREN, I have run couple of Java based applications like Cisco Transport Controller (CTC), Adaptive Security Device Manager (ASDM), LAN Management System (LMS) etc.
