Here’s the output on my machine /Users/powers/.jenv/shims:/Users/powers/.jenv/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin. jenv paths that are prepended to the standard PATH directories. Restart your Terminal, run echo $PATH, and verify the output contains. Run these commands to update your PATH: echo 'export PATH='$HOME/.jenv/bin:$PATH'' > ~/.zshrc Jenv uses the shim design pattern to route commands to the appropriate Java version. This blog post shows you how to get jenv setup on your computer and how to use the important commands. Spark developers should use Java 8 for Spark 2 projects and Java 11 for Spark 3 projects for example. Running multiple Java versions is important for Android and Apache Spark developers. It also makes it easy to seamlessly switch between Java versions when you switch projects. HelloWorld.Jenv makes it easy to run multiple versions of Java on a Mac computer.

We are mapping the local directory with the directory: /usr/src/myapp inside the containerĬreate a docker-compose.yml file: version: '2'.

Here we are specifying the Java container running version 8 of the SDK ( java:8 – to use Java 7, you could just specify: java:7).

Project dependencies are installed within the container – so if you mess up your config you can simply nuke the container and start again.Very easy to switch to different versions of Java by simply changing the tag on the container.

No need to set up any version of Java on your local machine (you’ll just run Java within a container which you pull from Docker Hub).You can simply run your application within the official JDK container – meaning that you don’t have to worry about getting everything set up on your local machine (or worry about running multiple different versions of the JDK for different apps etc)Īlthough this might not help you with your current installation issues, it is a solution which means you can side-step the minefield of issues related with trying to get Java running correctly on your dev machine! An option that I am starting to really like for running applications on my local computer is to use Docker.

Use jenv to install java 8 mac
