This is very interesting for serverless-compute and one-offs in Kubernetes A REPL (read-eval-print-loop) tool, JShell, was added to support interactive programming, similar to what is available in Python.Modularization also enables code to be refactored for easier maintenance, through a self-describing collection of code, data, and resources. The introduction of modularity to better support scaling down to small computing devices.However, the biggest differences between Java 8 and Java 11 are: In above command I’m pointing JAVA_HOME to 1.8 version explicitly.Ĭaution – Java 1.8 does not support short hand for version i.e -v instead you have to type : java -version full command to get the output.There are always a lot of little things that go into a release of Java, or any product for that matter. Lets make 1.8 as default version by running : export JAVA_HOME=`/usr/libexec/java_home -v 1.8` So What else we have to do ? Let’s explore that !įirst we will list – all the java version installed on machine by : /usr/libexec/java_home -V Now after this step if you will try – doing java -v still you will not be able to get java 1.8 as default environment. I’m installing Java via brew – which I personally believe is easiest way to install Java on mac – brew is a package manager for Mac OS like Chocolatey for Windows.
Then as all I thought no worries let me install the Java 1.8 and day will be saved, so for that I ran this : brew cask install adoptopenjdk/openjdk/adoptopenjdk8 So when I did something like java -v on cmd, got below response: Which in turn is not supported by Jenkins Latest version as of Feb 2020.
Problem started as I had Java 1.13 as globally installed. This problem statement came when I was playing around with Jenkins setup – As we all Jenkins still demands Java 1.8 ! and not higher. Hi Everyone – Today we are going to discuss about how to have two version of Java Development Kit running in MAC OS and how to switch between them.
